Like others here, I was trying to figure out how you're getting away with 2.4 wpg of T5 light without major algae issues (insanely jealous), noticed your first post said 24" as opposed to 24w, and thought they might be 24" 18w tubes, which would have made more sense to me.
I have a 55w AH supply retrofit over my 33g tank for 1.66 wpg and prior to adding regular large doses of excel, I was having constant BBA and GSA issues. Even with 20 ml of excel a day, I still have some BBA (and my vals hate me).
All I can figure now is your floaters are really cutting down the intensity into the tank, or your fish must be really heavy breathers to kick out enough CO2 to keep up with that light.
Or maybe these are NO T5 and not HO. (??)
I guess when my excel runs out, I'll try removing the reflector from my light, and/or add a bunch of floating plants, maybe hunt down some of those fish that are training for the olympics too.
