I'm not sure as I haven't tested them in far too long. My systems are nearly devoid of corals right now as I had a family emergency that kept me from home and subsequently I lost almost all of my coral from not being able to care for the tanks. I am going to be starting back up though. I'm sure they're sky high. Will I first need to get levels down to an acceptable level before dosing? I know that nitrate will not be consumed if phosphate is limited, but right now it should be plentiful...Not really anything else to worry about. It’s a good way to make food for filter feeders and even feed many corals and sponges and such directly,
what is the nitrate now? Phosphate?
