The brown algae is diatoms which feeds off of excess silicates in the water rather than sulfur. They are self limiting and usually go away on their own.
here,this is the best picture i can give you. i want to make sure that you still have the same opinion.
Question: will my grass dye?
Well that supposedly "brown algea" is not stopping , its getting worst. i am still having the same symptoms has before, seems worse. My nitrate his now at 10ppm instead of 40ppm (good). i am adding pps-pro 3ml for all types every day, and my light is closer of 1 inch. I only add filtered water from store(i always do,) and i am going go get my water from another place, that i can get steam water instead of filtered.
