Here are some pics . . . .my sand just started getting this stuff on it. I am using an ro system . . . I believe I was over-feeding. . . Cut back about a week ago. Someone told me phosphates. . . I purchased a brown power that is supposed to remove phosphate, but now about 5 days later . . Still there. Any suggestions?
Thank u
