I've been struggling with yuckiness that I've determined or am pretty sure it's cyano. It's brownish in color with some red filaments. I just kept assuming it was hair algae but after looking more closely, I think it's cyano. I have high nitrates (sailfert between 25-50) and obviously phosphates since I do have algae as well. So, I've been reading and reading and I've decided I'm going to treat the tank with chemiclean. Does anyone have any advice from using this product? I want my tank to look good again! Thanks in advance for any help!
