Still having some issues with this brown/diatom algae. Water tests: pH 7.2, ammonia 0, nitrite 0, nitrate 0. I have ordered a phosphates test kit to check the tap water and the tank water, and also a phosphate and silicate remover to see if that does anything. Reduction of feeding, upping of water changes and less light haven't seemed to have an effect. The only thing these two tanks have in common that the three tanks I have that don't have the brown algae is that they both run on bio-wheel filters only, and the other tanks have canisters. Just a thought I had. I had scrubbies in the HOB filters, and removed them (left the other mechanical floss) thinking there may have been too much gunk buildup in them, but that hasn't seemed to make a difference either.
