ok I know a pleco or some kind of algae eating fish is not an option because my 10" Trimac and 9" Red Devil in the 150 gallon will rip them apart. I know lights create algae but I like to keep them on for about 8 hours a day cause i like to look at the fish. My problem is that I have what looks to be brown algae. Only on one half of the tank because I usually only leave the one light on. I clean it with a brush but it's back pretty quick. I was told my sandblasting sand can cause some of this brown algae. Its not stringy or fuzzy or anything its just brown covers the side glass and the river rocks in the corner. Is there anyway to keep it away with like a phosphate remover media??? like I have no plants so i dont need phosphates in that tank??? will this stuff work??? will it effect my fish in any ways???
