My SA cichlid tank is totally green. I'm having a free floating algae bloom. My Seachem Clarity clears it for a day, then it is green again in the AM. Anyone had any luck with anti-algae treatments? I had this problem with my tetra tank, but the Seachem stuff cleared it up in a couple days. This is a show tank in my living room and it looks like a stagnant pond! Ick!
