I am skimming pretty good, also running new gfo and carbon and taylored aquatics phos destroyer.

I used to use IO but cant get it anymore so I switched to Seachem reef, but not sure when although it may have been around the same time. Because i remember checking the Mag content of the first batch and thinking it was really low. Turns out my mag kit was going bad and I was getting low readings on the tank too, thus causing my possible Mag overdose. I have let it lower itself slowly by not adding any new Mag suppliment for a month or so. I have switched now to Seachem marine salt to see if perhaps the last pail may have been bad.???
