I have noticed that in all my tanks, that one in particular never gets any algea growth and I mean NONE. Now I was wondering if this is because it has the best water circulation due to so much filtration. Does more circulation in tanks help prevent algea growth? I dont do anything different to this tank over my others but it always seems to stay spotless. Also I am sure some of the helping factor is that I have very low wattage lighting over this tank. Anyway, what do you people think?
