I am struggling with hair algae and I'm not sure what to do about it. I pick out as much as I can and scrub the rest with a tooth brush. It's not out of control only because I do this every day. I've been doing frequent water changes and have been aggressively skimming. My nitrates and phosphates both read 0 and I also checked my RO and that reads 0 as well. I've cut back on feeding and on my lights but still no luck. I've added a algae blenny and emerald crabs but they don't seem to be helping much. I also tried running phosphate sponge just in case. I had a large diatom and cyano outbreak as well but that has cleared up. Any more suggestions on what I should do? Starting to get very frustrating!
