    New Article on LEDs and coral biology

    Hi tony. The PAM meters used in many of these tests work by firing pulses of light at select frequencies in the blue range nearest peak photosynthetic absorbtion point rather than full spectrum light. Dana however does a bit of a juggling trick using both the PAM meter and a daylight halide in his non field studies. Personally I don't think it matters too much with regards to what situation the coral is tested under as by definition corals are adaptive to any given light field over time... The main thing is that we understand what frequencies are the major driving factors and how the saturation at those frequencies effects the response in the coral...it's a bit like saying a photon is a photon is a photon...the coral isn't concerned how its created or originated, its only interested in the frequency and its relative saturation of that frequency. All other frequencies are simply bounced, absorbed into the skeleton or bounced as long as the main frequency areas are coverd to a satisfactory degree of intensity...I don't think the coral is botherd wether its lit by the sun, a halide, a T5 or an LED as far as the source is concerned.

    New Article on LEDs and coral biology

    Hi Tony... ................................................................................ Hi Simon...an informative article, thanks. It has raised a few questions though. I see that you use Micromoles as a unit of measurement for the amount of light falling on a given target area (m2). This measurement is based upon how many Photons fall in a given area over a specified timeframe (micromoles 1s m2). The implication of this is that Saturation for instance can be measured purely by the amount of photons hitting the target and not by the energy carried by that photon. I had always assumed that it was the energy delivered by the photon that powered photosynthesis rather than the physical action of the photon itself. I was under the impression that it was the watts 1s 1m that determined the amount of photosynthesis that was generated. I ask because if it is watts rather than micromoles then we could easily be misled by light meters that read in micromoles. An example of the difference is that you would need 40% less Photons at 420 nm than at 700 nm to produce the same amount of photosynthetic activity. Micromoles are fine when used with natural sunlight as the symmetrical geometry of the spectrum means that the different wavelengths more or less cancel each other out and the mean value dominates. However with aritificial light, be it fluorescent, halide or LED where the spectrum is both skewed, asymmetrical and full of spikes at different wavelengths, micromoles become a much less accurate predictor of what energy is arriving at the target. Of course, all of my rantings are just piffle if my basic understanding of what drives photosynthesis is wrong, so I stand to be corrected. The main reason I use micromoles is that all of the data collected on compensation / saturation / inhibition using the Pulse Amplitude Modulation Fluorometer uses micromoles as the unit of measure, so I felt in this instance it was important to stick to the same relative unit (plus its one we can all relate to)..i know during research for the article which included various forays into architechture and engineering that watts was a common unit of measure in such circumstances when looking at the energy uptake characteristics of things such as roofs, or in engineering when looking at how a given surface would respond to exposure to different intensities. I can only assume that the main reason for this is that they are looking at a much more variable range of uptake under differing circumstances which would dictate a need to factor differing energy uptake relative to specific frequencies...whereas with pretty much all corals we have two fairly fixed areas of interest relative to the photosynthetic response, so there possibly isn't such a crucial need to factor the relative energy delivery on a per photon/type basis....I don't know the full ins and outs of the PAM meter process, but this may well be something that is automatically factored for..? Whilst on the subject of Photo saturation/inhibition, you sort of suggest that these phenomenon occur as a result of the amount of light falling on a target at any moment in time. Is this the only effect or is there a cumulative one as well, and if there is a cumulative effect (i.e extended exposure at a level below that of expected photosaturation), how can we tell the difference between "enough light for too long" or "too much light for the right length of time". Once photosaturation has been reached, will a coral recover (start photosynthesising) if the light is simply dimmed, or does the coral need a period of relative darkness to "reset its switches". Its not an instantaneous response as such because the photosynthetic machinery takes time to do the processing at any given saturation level and at a given surrounding flow rate (all of these processes are tied)..What the exact response time is, I don't know (its probably structure, pigment and zooxanthallae type dependent), but I do know that in testing, corals are usually placed in darkness for around 30 min prior to any measurements being taken to ensure that all the photosynthetic switches are in the open position and ready to receive light....I would hazard a guess that photo saturation could be reached literally within minutes if the coral was exposed to significantly high saturation levels and there was minimal flow. From my understanding, If the coral is exposed to levels below the saturation point, and all environmental variable are maintained such as flow, then the coral wont go into inhibition and will maintain a constant rate of photosynthesis, but the degree of ware to the mechanism will also be relative to how hard it is being driven and for how long....This is why, even if a coral is exposed to levels significantly below the saturation point but for an extended period it will eventually succumb as the mechanism is suffering cumulative degradation at a rate faster than the repair process is occurring...hence the need for the dark period so the process is halted completely. Dimming will certainly help the process imo, especially if the periods of both high exposure and dimming are of a short interval, but the difficulty would be in knowing at which point the coral passed beyond its saturation point and at what level of intensity..Thats one of the reasons for combining both the extended sunrise/sunset phases mentioned in the article, overlapped with cloud cover simulation to bounce the corals as much as possible between the saturation and inhibition points (call it a compromise between gaining colour and gaining growth and energy reserves). I still think that even in this case, some care needs to be taken however with regards to positioning relative to depth for the species you are looking at. regards

    2. The big issue of angle of incidence and how crucial a varied range of angles of incidence may be to most species that we could classify as mid to upper reef dwelling, rather than deep water species that are attuned to light from a narrowing range of incidence at greater depth but at much lower concentrations that are easier to handle. I think its a fair bet looking at the current research that most if not all of these upper reef species are actually gaining most of their (pre saturation point) energy during the early and later stages of the day when light levels are at a much reduced level, whilst passing into photoinhibition throughout the peak period. accepting the fact that on non clear days, they have the added bonus that the periods of energy gain will be switched around with little energy uptake until the mid phase when light levels are intense enough to drive the mechanism efficiently but not so intense that it is driven into overdrive.. Heres a big hunch.. I think one of the key reasons we have been so successful with lighting methods such as halide and T5 is simply because we have been offering light at such a wide range of angles of incidence and subsequently different intensities across the corals entire surface, that we have 'by accident' been replicating the very thing that many of these corals are adapted to take advantage of...Ie that is the ability to shut down areas that are over saturated, whilst still taking up energy efficiently across alternate regions that are receiving light within the ideal ranges. (a simple compensation process of counteracting a negative situation with a positive)..In effect weve been offering our corals morning, mid day and afternoon light fields all at the same time. This is one of the reasons that im concerned with narrow focussed LED's...Not only because they have the potential to drive the upper facing areas of a coral into prolonged or deep photoinhibition, but also because they omit the possibility for the coral to counteract that issue by taking up energy in other locations to an effective (counteractive) degree...You simply cant generate energy if there is no source in the first place.. As for switching to LED....well, there's no doubt that you have a huge amount of adjustability with any of the current upper bracket LED systems, giving you the luxury to replicate nature to a much finer degree, and theres no doubt that the spectrum is there now.... Personally I think there is still much we need to learn about the corals themselves, and I think we are in for many revelations as time goes by...in the mean time I tend to look to nature as the model, which inherently points me towards non-lensed LED's with a wide beam pattern as an expansion on our existing successes with other light sources...I think all too often we loose track or even fail to realise 'why' we were so successful with certain methods in the first place. regards

    New Article on LEDs and coral biology

    Hi Connor. There is no escaping the fact that the day of LED has come. We know from current research exactly what a coral needs and what it can quite easily do without as far as spectrum is concerned, so the old arguments over different light sources (T5/halide etc)being suitable or 'better' from a spectral standpoint are now pretty much null and void (cheap nasty Chinese units aside). The main advantage with LED is that you can channel energy into specific wavelengths that are essential, whilst minimising or completely avoiding through adjustment, those that serve no purpose or are directly damaging. The challenge rests in my opinion in two areas. 1. Finding a way to not only measure and control the outright PAR delivery within margins of realistic usability as far as the coral is concerned (much of which is covered in the article), but also have the capacity to know or measure the 'ratio' of PAR across the various wavelengths delivered. I have a nagging feeling that the PAR ratio is something we have generally ignored or in many cases completely misunderstood. We generally think of PAR as a total figure of usable light, whilst ignoring the fact that corals have distinct ranges of frequency that are much easier for the corals zooxanthallae to utilise than others. ie the 410-490 and 650-700nm ranges with minimal effort required on the part of the coral in adaptive/distortion pigments to hit those ranges. Our PAR meter however measures all light within the 400-700nm range. even light between the 500-650nm ranges which is a far less efficient range as far as the zooxanthallae are concerned. Now you might be sitting there thinking, yes I know about that stuff....but lets look at things from another angle. We know from experience with halides that when we compare 3 different lamps of the same wattage but differing kelvin rating we will see a general trend of reducing PAR as we move up the K rating scale from say 6.5K to 20K...and more often than not a corresponding reduction in growth rate of any corals housed under those lights, tied with an apposing increase in pigmentation. (ie low growth but high pigmentation at 20K---to high growth and low pigmentation under 6.5K)but we also know that PAR meters generally 'under' read at the blue end by varying margins across the crucial 410-490 range....so here's a hypothesis.. If we could compare two lamps of the same wattage, one at 6.5K with a very high PAR, and one at 20K with a much lower PAR, by filtering out all light above the 490nm threashold, and factoring in the error factor for the meter, could it be the case that the 20K lamp is actually kicking out far more PAR in the 410-490nm range than the 6.5K lamp that is distributing its par (energy) across a much broader range. If this IS the case, then by definition we have to consider one big flaw in our theory that higher kelvin lamps give lower growth rates...It is equally possible that they are actually 'inhibiting' growth by driving the corals into photoinhibition across the light period by concentrating high amounts of energy into that spectral range, compared to the lower kelvin lamp that offers a much lower concentration of PAR within the 410-490nm range (even if it has a higher outright PAR).....This lower concentration within the 410-490nm range in 6.5k lamps may well be at a level much more in tune with 'or just below' the corals photo saturation point (hence the higher growth rate), simply leaving the coral to produce pigments aimed at bouncing light of the 'non essential wavelengths away. (a low energy expenditure process). Looking at the typically stronger pigmentation encountered in corals housed under higher kelvin lamps, this may equally be a sign of 'over' saturation in the key frequencies resulting in the corals need to produce protective pigments aimed at controlling over saturation by those frequencies that can drive the photosynthetic mechanism into photoinhibition, needing a consequently higher degree of energy expenditure in the ongoing repair process. What we are saying here is that blue light is good because its the easiest to utilise with minimal effort on the part of the coral, but only up to a certain point of usability. It is quite possible that in an effort to provide what we consider a good PAR level using higher kelvin sources, we have in fact been pushing much more PAR than we 'think' into our corals, with the resulting reduction in growth more attributable to over saturation and inhibition, rather than the common assumption that the reduction is due to the lower outright PAR level compared to a lower kelvin source of equal wattage... This is one concern I have with LED and the tendency for people to ramp up the blues whilst reducing the whites...often under the 'impression' that they are lowering the intensity....You may well be visually, but as far as the coral is concerned all you've done is reduce the intensity of those frequencies that possibly arnt being utilised as much, whilst leaving the coral still highly exposed to PAR levels within the 410-490nm range that are well above that required for a well balanced growth/pigmentation ratio. Until we do more research in this area and can compare relative concentrations of PAR across different sources within specific frequency ranges rather than the whole 400-700nm range, we are realistically working blind. .....
  6. Hi folks...just a heads up... A new article that may be of use to some. It's a big read becouse its a big subject but hopefully you'll enjoy. If you have any questions about any of the subjects coverd I will be happy to discuss and expand on them as long as its kept polite...something this board is known for which is nice.... http://www.reef-eden.net/corals-conifers_and_led-a_new_perspective.htm Regards Si.

    Giesemann Futura In All It's Glory!

    Hi All, As some of you may know, Giesemann's long awaited Futura has finally started hitting the shelves. Giesemann being the perfectionists they are, wanted to hold back on final production pending the addition of yet more colours to fill out what is one of the widest spectral distributions on the market, and further updates and modifications to what has to be said is the most flexible yet user friendly software control package of any LED lighting system out there. Offering up to 30 controllable channels, full and infinitely adjustable weather simulations, a real time lunar phase simulation that can be set to track your local Lunar phase in one easy step, Independently controllable modules that accept different maps to allow different lighting scenarios to be played out within given sections of an aquarium (such as an area specifically for lower light deeper water LPS etc)...If you want to get really creative you can even set the modules to perform just like the sun in nature, relative to intensity, spectral shift from morning to night, and set the peak intensity to travers across the aquarium in a gradual arc from one end to the other, thereby limiting the stresses of prolonged high intensity static exposure on corals. In all, an incredible 4320 set points can be plotted across a 24hr period. The free software which is compatible with PC/MAC/IPAD/ANDROID/IPHONE not only allows full remote control via Bluetooth, but also allows you to save an infinite number of profiles which can be saved/modified for later, uploaded and run, or even shared with other Futura users. Unlike many other companies, Giesemann weren’t that fussed about winning the never-ending PAR/PUR war which by and large has become a meaningless battle, understanding that in the big scheme of things, the Futura along with most other upper end LED units already deliver far more usable light at peak output than is actually required to get good coral growth and stunning colouration in even the most demanding shallow water SPS corals, so instead concentrated on the ‘way’ the light was delivered and the ‘quality’ of that light. In the end they went for higher output loss free optics rather than the traditional secondary lenses to give a much wider spread and more even distribution of light across emitted the light field, and better mixing of the different frequency outputs across the LED array, thus preventing those annoying colour spots all too common in units using tight beams, especially as you get nearer to the source point. This wide angle output also puts light into the aquarium at shallow angles meaning that just like nature, corals receive light from a wide array of angles including their sides, enabling them to attain much better all-round photosynthetic capacity, and not just from above which is commonly an issue with more tightly focussed platforms. Ah, but what about depth punch though?. Well, each boards output, is spaced and designed to overlap its neighbour, thereby increasing the overall intensity without the need for excessive focussing to attain that depth at the sacrifice of even distribution across the whole lit area. As for spectrum, well they didn’t hold back there either with 7 different colours, running from a low upper band UV 390nm violet, through 5 other colours, right up to the 790nm red. And just to prove its not all smoke and mirrors, here are a couple of video's showing just what the Futura can achieve, and what the user can do with that incredible software package. The tank in thse video's runs full time on a futura (just in case there are any doubters out there) For full specifications visit: FUTURA LED

    Polyplab's Reef Roids Now Available!

    We are pleased to announce our appointment as sole UK distributor for the respected and innovative Canadian manufacturer 'Polylab' with their first product in the range; Reef Roids. Reef Roids were originally designed for the scientific community and specifically for the maintenance of one of the hardest to keep species- 'Goniopora'. They were later found to be relished by a very wide assortment of corals and other filter feeding invertebrates making Reef Roids one of the most complete all round reef aquarium foods on the market. The unique aspect of Reef Roids is that, unlike most artificial coral foods, they are not manufactured from the usual assortment of bulk ground ingredients such as krill, fish meal and fillers which are dosed with amino acids to elicit a feeding response. Reef Roids are instead manufactured from pure high density marine zooplankton thereby offering the most natural and realistic range of food types and particle sizes (150-200UM) available to the widest range of corals and other invertebrates; many of which rely on key scent markers and particle sizes to identify prey as applicable to that particular species. Users have commonly noted that many zooanthids, mushrooms, goniopora and a whole host of hard corals both LPS and SPS to show a remarkable feeding response. Additional noted changes with long term use have been increased growth rates and stronger colouration due to the more natural range of essential trace elements and amino acids found locked with zooplankton. Reef Roids mixes remarkably well into water and does not float to the surface like many dry format coral foods, is ensures a long retention time in the water column to minimise food waste and allow maximum uptake by the corals. It's fine particle size also means that the food will remain neutrally buoyant to pass through most mechanical filter medias repeatedly for several hours after addition before being either consumed or gradually removed by other filtration equipment such as protein skimmers. Having attained critical acclaim in the US and being a much sought after food in the UK for some time now, we are happy to announce the availability of this product in 2 sizes- 40g and 60g. For contents and directions on feeding please visit Reef Roids Pricing is as followed: Reef Roids 40g- £14.99 RRP Reef Roids 60g- £17.99 RRP To find your local dealer stocking this product please visit Dealer List

    REEF-RODS (a new unique aquascaping aid)

    Please see below details of the latest addition to our ranges. Reef-Rods are a brand new and unique aquascaping tool for the creation of stunning rock structures in Marine or freshwater aquaria. Made in the UK from high quality aquarium safe clear acrylic, Reef Rods allow the safe and stable construction of rock towers (bommies) when used singly, or when used in multiples combined with plate rock to create stunning multi-level aquascapes with adjoining platforms, bridges or arches. Each unit consists of a wide and stable solid 10mm thick acrylic base with additional 10mm thick bonded centre support plate to spread load and add stability. Into this a solid acrylic rod is inserted which is held in its seat by a plastic screw. Rock can then be drilled and placed directly onto the centre rod, or cable tied around the rod which will act as a support structure. Being clear, any visible sections of rod will be virtually invisible once the aquarium is filled and will quickly coralline over to become just another part of the scenery. Once added to the aquarium, the base will stay hidden below the substrate or can be allowed to grow over with selected corals and fauna in the case of bare-bottom aquaria. BENEFITS. Allows stunning structures to be created with minimal effort and experience. Ideal for professional hobbyists, beginners, commercial builds, or those who simply struggle with aquascaping. Allows the building of secure rock structures with only minimal use of aquascaping putties or glues. Allows stable rock structures to be built away from the aquarium glass resulting in better circulation throughout the aquarium and a healthier system. (Ideal for gyre flow setups) The open nature of the rock structures combined with more efficient circulation characteristics allows more efficient use of the rocks biological properties, often resulting in more efficient filtration for a given amount of rock when compared to conventional reef-wall type aquascapes. Keeps the amount of live rock in contact with substrates to a minimum preventing compaction and dead areas where large volumes of waste can collect or be difficult to remove. Reef-Rods are available in 4 different standard sizes, and can be used in any aquarium from Nano to Monster build. (Oversize units are available upon request from authorised dealers) Example construction on the smallest RR-230 with a 12" high bommie using 3 main rocks and 2 branches Example construction on the largest RR-600 with a 32" high bommie using 8 main rocks and 3 branches For further information and pricing, including downloadable user manuals, please visit: Reef Rods For authorised dealers, please see our dealer locator. If your local retailor isnt a stockist, please feel free to point out our web site and ask them to get in touch and we will be only too happy to help. Kind regards.

    Po4x4 Product information

    Please feel free to ask any questions regarding the use of Po4x4 on this thread and we will endevour to answer them as quickly as possible. Product information: PO4x4 phosphate removing media. As any successful aquarist will tell you, keeping control of nutrients is one of the main objectives if you are trying to keep fast growing, vibrant, healthy stock and keep problem algae at bay. Phosphate is one of the major contributors to excessive and problematic algae growth, as well as an inhibitor to calcification in stony corals leading to poor growth and colour. PO4(x4) is the cleanest, most advanced, and most efficient phosphate removal media available to the hobbyist today. Unlike standard GFO (granular ferric oxide) media’s designed for phosphate and silicate removal in both saltwater and freshwater aquariums, Po4x4 is a super clean, no fuss, rechargeable, micro-bead polymer that can absorb up to 4x the amount of phosphate and silicate compared to many competing brands for a given volume of media used. Absorption Capacity: Just 250ml of PO4(x4) will remove up to 3.0ppm Po4 from 4000lts of saltwater or 3.0ppm Po4 from 8000lts of freshwater giving PO4(x4) one of the highest absorption capacities in its class, commonly up to 4x the amount taken up by competing brands when comparing volume to cost ratio. PO4 (x4) Phosphate Remover is a unique chemically engineered polymer based mini pellet bound to very pure FeOH2 that is durable enough to withstand heavy use in fluidised reactors with no risk of abrasion and fines release.. Both the polymer as well as the Iron molecules are able to bind PO4 without any risks of leaching back to the aquarium. By combining these two traits we have increased the binding efficiency to very high levels. In addition, PO4(x4) contains only Iron hydroxide, compared to normal GFO which consist of a mixture of iron hydroxide as well as iron oxide of which only the first form can bind phosphate. This means that PO4(x4) with its higher content of Iron hydroxide can bind much more PO4 than many alternate brands for a given volume of media. Surface area: By keeping the pellet very small (much like the consistency of De-ionising resin) PO4(x4) offers a much larger surface area for volume compared to most other media’s. This means that the media has much greater contact with passing water for its volume when used in a fluidised reactor. Plus the media is easier to keep fluidised effectively due its low mass which means less tendency to clump with resulting channelling and loss of efficiency. The Clean Option: Being a polymer, PO4 (x4) won’t release any fines or red clouding into the water column unlike standard GFO medias which can irritate and stress some corals, or if severely over fluidised, lead to fines accumulation in substrates. This means no need for rinsing several times before use, and an easier time for the hobbyist when handling the media or cleaning out a reactor. Just place the media into a reactor or media bag* and the media is ready to go. *for maximum efficiency, fluidising is recommended to increase contact area and contact time, although PO4 (x4) can still easily be used to good effect in a high flow (large micron) media bag placed in a high flow area such as the sump, or rear compartment on Nano-aquariums Recommended Dosage 25-50ml per 100lts of system volume. (maximum recommended 100ml/100lts Rechargeable: PO4(x4) can be recharged up to5 times by using PO4(x4) regeneration powder which flushes the bound phosphate and silicates from the polymer via a strong chemical action. This means that over the long term when combined with its superior absorption capacity, PO4 (x4) is one of the most cost effective methods of removing phosphate and silicate from aquarium water, with a total absorption capacity (after factoring in 5 x regenerations) in exess of 20x that of most other brands. Please note that to get the best results, It is highly recommended that our user manual is downloaded and followed which can be found here: Po4x4 phosphate remover You can also view a video demonstration of how much fluidisation to aim for here: http://www.youtube.com/watch?feature=player_embedded&v=LKVFqNewOdU You can also see comments and photos from an end user review: PO4x4 Review If you still have any questions after reading the user manual and observing the video, please feel free to ask in this thread, or send your question via email to the address on our home page.

    A Little about R-E-I

    Firstly let me just say thanks to jas and Linds for accepting our request for a section on IR. Many of you will know me from my various ramblings on my private website www.reef-eden.net , in magazines such as Ultra Marine,ramblings on here, or will have seen me do presentations at various events over the yrs, so im sure I am no stranger to many of you as a hobbyist first and formost. Reef-Eden international was set up in late 2011 as a progression of that passion for marine aquaria and the hobby as a whole, with a simple goal in mind, to distribute via the LFS high quality products that have been through the hands of a seasoned hobbyist so that the end-user can be assured of the validity of advice offerd, the quality of the product, and above all else have faith in the purchase they are making be that media, equipment, addatives or any number of products we are working on at any one time. Our second goal was to support the industry, with specific attention to the brick and mortar LFS, the place we all rely on at the end of the day in one way or another, and the foundation of what we all hold dear..the ability to buy exotic animals to place in our little glass boxes in the hope we can have a slice of the ocean in our living rooms, so it will come as no surprise that there are two sides to the company, firstly the development and supply of quality dry goods and equipment to the marine retail industry, and secondly the supply of high quality landed and rested livestock to the LFS via a team of dedicated collectors around the globe and in partnership with one of the UK's newest coral importers. we dont consolidate, we actually handle, rest, feed, and condition all our stock before it even goes to the LFS to ensure the best quality possible by the time it lands in the hobbyists aquarium. Sadly, as a trade supplyer we do not supply direct to the hobbyist under any circumstances. but we do have an ever growing list of authorised dealers that can be found on our website Dealer List where you can find our products or order a particular item if not currently carried. If you would like your dealer to stock R-E-I distributed corals, then please feel free to ask them to get in touch with us and we will happily send through availability lists which they can order from. Over the next few days we will add product information bulletins where users will be able to find information on specific products, get sneak peaks at up and coming products, and have the oportunity to get help and support where needed. Kind regards
