I tested magnesium today for the 1st time and it came back at 1000-1050 with Salifert and I am wondering if I need to do anything, and if so what? I have read the test kits can be very inaccurate, and to dose it based on calcium, so have never tested it and hoped the all for reef would keep it where it should be, the tank is only 3 months old with 2 small frags. I started dosing All for reef a few weeks ago and made sure my Calcium and alk were where I wanted them. So I have those where I want them, alk 7.5 and calcium 440. Just not sure what to do about Mag now.
