My 180 is full of brown hairy algea. It's growing all over the rocks. I tried to siphon them out as much as i can and it grows right back. I'm using RODI (new) filter. I also trying to dose two part, followed the instruction, baked the baking soda. When i try to dose the 2 parts.....the hairy algae grows even faster. I have phosphate remover in my skimmer DAS 2 skimmer compartment. Will get a phosphate reactor soon. I'm also running carbon, don't see like it's working at all. I have been feeding much lightly than usual. Any clue on what's going on?
