Has anyone used this product to get phosphates down. I’m running rowaphos in a reactor and can’t get my number down I’m at .17-.22 it just won’t lower. My LFS suggested phosphate E, anyone ever use. Anyone have suggestions on what can be causing my phosphates to e so high and not lower with rowa phos, and it’s not over feeding I more than not go days without feeding just because I forget. I have quite a bit GHA as well.
