Why So Much Algea?

[ianeberle]

I have a 36 gallon tank with pressurized CO2 (1-2 Bps). It's full of plants with Eco-Complete substrate. The light is the 36 inch AquaticLife T5. I also dose liquid Flourish (N, P, K, and comprehensive). I have algae growing on the plant leaves and on the glass like crazy.

I thought the CO2 was supposed to kill algae? Could it be that the tank temperature is about 82 degrees? My 10 gallon tank has the same setup but it's room temperature (fluctuates from 71-75 degrees) and has no algae.

How long are you running your lights daily? Also what kind of algae do you have? CO2 doesn't kill algae. It aids plants in photosynthesis and growth which means that plants need more nutrients and are better able to out compete algae. When you have algae issues only run your lights 6 hours daily and no more than 8 once algae is gone. That is alittle warm for the tank, can you lower the temp?

How long has the tank been set up? Most,if not all, new tanks go through an algae growing period.
