I had my water checked the other day at my LFS and have a phosphate level of 2. They said water changes will bring it down and I know a reactor with phosban will too, but don't have one. Can I just put phosban in a filter sock and place it in my sump? Also any other advice would be good. All corals seem OK still just doesn't look like my sps is super happy.
