My tank seems to have gone south. I’m thinking I need more CUC as I think my numbers have gone down and my algae is growing faster then the CUC can keep up. I also had a drop in nutrients 2 ppm nitrate and 0 ppm phosphate. I think I’m on the up swing now though as I finally have 5 ppm nitrates. Anyway should I remove my zoa garden? How should I clean it?
