Calcium and magnesium issues

[sdeschutter]

Hey everyone I'm worried about my calcium and magnesium levels. When I tested yesterday Cal was at 330ppm and magnesium was 1500ppm. I have read that I want my Cal between 380-450 and Mag at 1250-1350. The Cal reactor has been going for a two weeks. Prior to adding the reactor I brought those two parameters up to proper levels then added the reactor so it was easier to dial in. My question is should I be concerned? And if so what should I do to raise Cal levels and lower Mag. Btw I have hand 4 sps frags in the tank since Boxing Day and they seem to be doing ok.
