Well, here is how my setup is so far. Its a 10 Gallon tank, using Nova Extreme 24inch T5HO Fixture, 10k White and 640 Antic with a total of about 5 Lbs of LR and 20 Lbs of LS.
The filter is an modified AC70 with a AC20 propeller, glass
glued to the side to force all water down, and the filitration is currently for debris only since the sand caused a lot of silt to float around; sponge filter, polishing pad, polyster, and LR. In a week or 2, after I get more LR in a couple days, the filtration will be a 1 inch sponge, 1/2 inch polishing pad, ChemiPure Elite, then LR, with either a LED light or a 6700k compact bulb for some algae growth.
I have my lights running on 7-8 hours a day, from 10 to 7 on a 5$ timer. I don't plan to carry damsels or angelfish but I'm going to throw my damsels in for the cycle in a couple weeks also. I think my beginner fish will be a Royal Gramma and a yellow clown goby.
Picture below is with 10k bulb only.
