A lot of people here are saying though that the issue is partially that there's no enough phosphate to support the corals, would reducing it further not make the issue worse? I'm just getting a lot of conflicting advice from this threadUse phosphate remover by brightwell. I cleared a ton of algae issues by getting an over size skimmer. I got a skimmer rated high bio load for 40gallons my 20 gallon tank and it cleared all my issues. Over sizing makes it more effective if you over feed, lots of fish, and algae.
