I was doing regular WC’s, but didn’t have a big need to dose, unfortunately I believe I starved corals. I had high nitrates, but no PO4’s. Lots of Coraline, plenty of reproduction, growth with some, but I kept killing Acros. I stopped using Chemi Pure Elite, switched to ROX, started dosing 50 ml 2- part daily, and added Matrix to my sump. A year later, I’m dosing 300 ml/2- part/ day, everything manually. I fed less more often, and cleaned more, and switched from LEDs to T-5’s. My killers were dosing NoPox and stripping nutrients from the system
