On the question of CO2, the only tank that used CO2 was the 20L in post 272. I hated it, as the fish I like to keep were not doing well with it. I still have my set up, but I do not think I will ever use it. I did use excel and ferts. Lighting was all T-5's. Some of the smaller single tanks may have been CFL's. Thank you!
