Well Brad first thing I would ask is what brand of salt are you using? Do you use any other additives? 1350 is good Mg levels, not sure what Dez keeps his level at but I have been told that 1400 - 1450 is optimal. I have not been able to test mine lately as my Elos test kit ran out of part c but I do know that I started to add Mg flakes from sivermax again and once I get a new kit I will test and bring mine up to level again. I think that SPS require more Mg, Ca and trace element to grow in our tanks as opposed to the ocean but I am in no way an expert on SPS that is for sure.
