Help
We like many of you light our algae in the sump 24/7 and with good results,but i have always thought that this is far from natural for the algae.This has been prompted in my mind after a short conversation on the subject with Tony,ie karnivor so
i have decided to have a go,possibly,at lighting the sump vise verser to the main tank.
So what ime asking you all to do is to do some digging into the advantages and disadvantages of lighting a sump 24/4 and post up your findings?,you never know,we may all be doing it wrong lol.

I use to run mine like that, I can't say the algae growth was any different and it didn't have and significant effect on the ph overnight. So far as the latter is concerned, the o2 reactor appears far more efficient.
That was on my 'old algae' setup. With the new ones, they are lit 24/7, and this may be slightly off-topic, but remember I was moaning about the cheato not growing under the low-energy lamps? Well, I replaced those over one tank with a proper grow light, admittedly it is 120W as opposed to 40W, but the growth difference is massive. Whilst the brighter lit cheato has nearly filled it's tank, that under the energy savers has barely shown any growth. I've been considering fitting a second 120W grow light to the other cheato tank and then splitting the lighting 12 hours on/12 hours off, alternately between the two tanks.. Tho my main reason for the 'off time' was to save leccy rather than anything else.

Firstly, the 120w light has had a huge effect on the algae growth. Whilst the algae under the old lights has barely grown in months....
...unlike the other cheato tank tank below which is pretty solid, they both get the same volume of dirty water and started off with the same amount of cheato.
I've been thru a phase of low-nutrient cyano buy upped my feeding and used some zeozyme+zeobak to tackle it. Whether the drop was directly attributable to the cheato growth I don't think I could say, but the bucket test is much better than it was several months back. I feed something like 8 cubes plus pellets each day and have 20 or so fish. Nitrates and phosphates are unmeasurable on the salifert kits.
Would I go back or remove it? No.
