Im getting some hair algae on the walls of my tank and on my plants. I know the profile says im probely getting it because of to much iron in my tank. I have been dosing the following: 20-40 Gallon Aquariums +/- ¼ tsp KN03 3x a week +/- 1/8 tsp KH2P04 3x a week 1 Cap Full of Flourish 3 times a week. 50% weekly water change What should i cut out to get rid of this stuff the Flourish? I quit dosing Flourish about 2 days ago no sign of it getting better yet but it has not got any worse i don't think.
