Sounds like your tank is overfed, but you don't. Are you sure no one else is treating the fish to a little snack now and then?

I find over dosing Iodine (Kent,brand may vary)and Essential elements(Kent,brand may vary) can lead to problem describe in the above.

Michael,

I don't know if a Ca reactor does anything for raising Mg. You should have a test kit for it to make sure what your level is at. Having enough Mg is as important as having enough buffer and Ca.

As for phosphate, with your excellent lighting, skimmer and refugium, I doubt that you would measure any phosphate. I'm pretty sure that whatever phophate nutrients that would be produced in your reef, that whatever your skimmer isn't removing that they are being utilized by your macroalgae.

Actually Bev using a Cal Reactor wil level out your Magnesium level to 1350 ppm
