Hey everyone. I just received my Hanna checker and honestly, I’ve confused myself on what phosphate level i should be shooting for. I keep reading that I need to be around .02. Today I tested with a .28 and started panicking. But I have no algae problems and my corals looks fine. If this level is too high should I run phosguard in my sump for 4 days and re test?
