I have what I would think was hair algea growing in it. The stuff is brown not green. I wanted to show some pics but it doesnt upload the way it use to I guess. Any help with that? I have a main pipe coming down from upstairs to the basement, it "T's" to the sump and the fuge. I haveit flowing low to the fuge and higher to the sump. Rocks cheato and magroves in the fuge and a Humm Humm trigger. I'm just wondering if the hair is suppose to be there or not???
