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
