Thought I'd do a little update on my upgrade, or at least the preparation for the upgrade.

If you didn't know, we are upgrading the existing nine year old 72x24x18 tank to 72x24x27, same length, same hieght but 50% wider which should give better options for scaping. The reason for the upgrade is because the current tank is getting 'grown out' and the narrow shape is not great for aquascaping with large colonies which tend to over-shadow each other.

It's a process that started back in January when the decision to upsize was first made.

Originally I was going to make the tank myself, I've done a few large ones before so am not afraid of it, but I found I could get one ready-made for £50 more than the cost of the glass including delivery and warranty, so once I'd decided on that, the order was placed at the beginning of March and the clock started ticking, will the new tank arrive before the my favorite acros breach the surface?

To help with the new scaping, I got some dead-live rock with interesting shapes out of Jasons butts which has been curing in the garage since the end of January. Once it got thru the initial curing cycle, I plumbed the 350 litre water butt into the main sump so it should be well seeded by the time I change over.

Of course, a new tank wouldn't be the same without a new stand, or two in my case. The first stand frame ended up as a workbench because I wasn't happy with the wood, but thats fine, I could always do with an extra bench in the garage.

Because of where the tank goes and to make it appear less imposing, as per the current stand, the tank overhangs the base by several inches. This, along with the fact that it was a non-standard 27inches wide means I couldn't use an off-the-shelf stand, that would just be too easy. I enjoy making things anyhow.

I suppose I could have made one from steel or block and beam, but opted for the more conventional wood, and of course, in true reefer fashion, over-engineered and capable of supporting a family of large hefalumps no doubt!
Fortunately, past experience has taught me to allow it to be partially dissassembled to make it a little eaiser to move into the house when the time comes and once in place I can finish it off. Since it is in it's dissasembled state, you'll have to make do with a sketchup view...

For those who don't remember, my system was upgraded with a remote sump two years ago. This will remain unchanged since it does a stirling job.

With the rock curing and the tank on order it was time to think about some temporary accomodation for the livestock. It was already decided that there would be no hope of doing any the changeover in a day let alone a weekend, even if there were no problems, it was just too much work.

We are undecided about what corals/fish we willl keep and what will 'go', so a temporary home was required. I got an IBC 1000 litre container from Martin (cass1) that I cut down in hieght to make a shallow 4x3 tank which I put in the garage, plumbed it into the sump and started brewing some water. Two hundred and seventy litres later, it's ready to be 'turned on', or it was until I realised that it was stone cold and dumping 270 litres of cold tank water into my system might upset things a little, so I had to go out and buy a heater, jeez does it never end.

(Quick photo before I finished the insulation & lighting)

I've got a cover for the 'jacuzzi', as Ben called it, that will be kept on it when the lights are off. The water was up to temp this morning so I began trickling it into the main system. After 24 hours I'll begin upping the flow.

I'm not sure what to do about the fish. The plan was to put them into this tank, but thinking ahead, it could be a nightmare trying to catch them again, think I'd need a trawler net.

Well, thats where I'm up to right now. I haven't got a confirmed delivery date for the new tank, I expect it be this weekend or next week sometime, so the plan is to be very busy between now and then!

Cheers!

Chris

(off to brew another 100 litres of water just for the hell of it)

(must start seeding the sand)

(must get some polystyrene tiles)

(must get some eggcrate)

(salt, gonna need some more)

Sketchup followed by Paintbrush, what an interesting combination :D

Are you skimming after the DSB and Caulerpa stage? How are you finding this?

Yes, only I don't have any caulerpa or cheato, it just dies on me. Skimming very well, doubt I could get much better really. Due to the slow tank/sump turnover it probably gets plenty of cycles thru the skimmer before going back to the tank.

Sound like a well thought out plan Chris, will be a great setup when it's done if your existing setup is anything to go on

The sump was done two years ago, I just included the diagram for reference.

The turnover is low, I know it's low since I measured it a month ago, I was expecting it to be 3 to 4 times an hour, but it barely made 2. The only problem I perceive with this is that stuff stays in the tank longer including detritus, but phosphates measure out at 0.02, nitrates are un-detectable and I'm a proficient feeder with three large tangs. With the skimmers pulling and returning water to and from the equipment sump, the water probably goes around the skimmers several times so should come back sparkly clean.

At first I just put the low flow rate down to the three 32mm tank outlets at the wrong end of the tank, the single 40mm pipe run from tank to sump and joining the sump system part way up the 200 litre barrel the outlet of which is a further foot higher. This effectively reduces the 'head' to something like six inches, it's not like have an under tank sump which you would get something like 4 feet of head.

However, I realised just a few weeks ago that the limiting factor at the moment is the return pump, the tank outlets are barely half submerged indicating that they could handle more flow, it's just that the pump I'm using isn't performing. I've been using a *cough* Grundfos *cough*, and never really thought about it, but it's just not man enough. I recently looked at the flow curves for it and when you work out the head losses of my system it comes out almost bang on what their specs say. So, yes, I'm going to change the pump, probably try an OR6500, but that won't be until after the tank swap is done.

The new tank will have better positioned outlets, hopefully, but I'm still limited with the pipework between tank and sump. The channel I cut in the concrete floor across the lounge won't take anything much larger than the 40mm out and 25mm return. There's a chance I may be able to squeeze an extra 20mm pipe in there as well for use in one direction or the other, but we'll wait and see. Of course, ultimately, if the tank-to-sump flow becomes the limiting factor I've always got the option of changing it so rather than joining the 200 litre barrel, it goes straight into the equipment sump, that would give a good five foot of head, less bends etc.

But thats all for a future date, right now I've got enough to deal with!

This morning I started the flow into the holding tank, just siphoning thru some ro tube, so by the time I left for work it had become part of the system. I also chucked a couple bits of LR from one of the sump tanks into it and gave it a good squirt of VSV to help things along a little.

Here's a pic of the rock pool bucket where the new live rock has been curing and seeding for the last couple of months.

Posted Image
(Blimey, what a crap picture, I'll dig out my camera tomorrow)

This is fed via a siphon from the sump and just gravity feeds back to it. Buried in the bottom is a large powerhead. Currently, the outlet from the new holding tank exits into it which is fine whilst it is just being trickle fed, but when I crank up the flow I don't think the rock bucket return will cope so I'll plumb in it's own return. I was going to do it this evening but was an elbow short.

Instead, I gave the sand another rinse in fresh salt water after being washed at the weekend, and then made up a super-high-calcium-strength mix of salt water and left it soaking in it. Hopefully now, when I come to use the sand it won't cause the calcium reactor to undergo meltdown.

Finally, turned back on the ro machine for another batch of salt water.

Well, one step closer. Last night I turned on full-flow to the holding tank. This is now being fed from the sump using an Eheim 1250 that I borrowed off Martin. I've now got a lot of water flowing around all over the place, hopefully I won't have a power cut otherwise things are going to get wet!

The plan now is to empty the display tank at the weekend ;)

Well, I couldn't put it off any longer, the first few corals have been moved this afternoon. Started with a few 'loose' ones, I'll need to remove the hood and all to get the rest out tomorrow.

Thought I'd take a few snaps as I went along...

First, a couple of echnopillias and an oxypora...

Posted Image

Green/yellow milli...

Posted Image

Couple of acans...

Posted Image

Whilst they were out, got a nice macro shot too, not that I was intending to do so...

Posted Image

These were all taken outside in the sunlight.

And in their new home. Because the water is only 12 inches deep and the 400 watt lamps about 16 inches above the surface, I put the LPS under a blue radium and the SPS will go under a reeflux 10K.

Posted Image

And all covered up to conserve some heat...

(Looks like the campers have moved in!)

The tank already looks bare :good:

More pics tomorrow as we really get into action.

Well, you've got to try and save a bit of leccy. The heater I stuck in the holding tank has only been on for 2 hours in 6 days. The other thing is to prevent condensation in the garage. I reckon there is more insulation on that tank than in my loft!

Sunday, I started by removing the hood leaving the fish wondering what was going on...

Posted Image

By lunchtime things were looking a little different....

Posted Image

I'm glad I did pick a large holding tank, it's surprising just how much room all the corals take up...
