I took the top two off line because:
- sump is just too small, I had to top off daily, and I cant get down there daily
- I found if something is hard to work on... you don't.
I mostly just propagate RBTAs and mushrooms in there now... you know, if I could find somewhere else for my RBTA propagation, it would be a great system. But I have to cover the drains with sponge, and the sponge needs to be cleaned or they overflow, and if there is no sponge the BTAs go through the pipes... which over flow... Did I mention it overflows alot... lol
The lights are t-5. With one ATI Blue + its about 60PAR and with two its about 90... if I recall. I haven't tested for a while. But I know its plenty of light.
