My all is a stable 7. Cal still stuck around 310, I never been able to get it higher than that since I started my tank. Dunno why. Mag around 1200. I'm going to JL today to buy a phosphate test kit. I'm running one of those phosphate remover bags passive in sump in the same chamber as my carbon bag. Maybe the carbon is making it neutral? Should I run the phosphate bag in my filter sock instead? I was gonna order another led fixture today as well because I only have 1 16" fixture for my 4' tank this whole time. Also the tricoloured nana colony I got from you is starting to brown out the same time most of my other sps are as well. So I'm not sure of my lights are losing quality over time or not.
