Good to know it's worked for so many. Kent has to be pretty happy about this alternate result of their mag dosing and only their mag.
Jim, were you dosing the amount to raise it 18.3ppm or a higher dosage? Also, I'm wondering if I did this for 6 days, waited a week and then continued until my mag was 1600 if it would be easier on my corals. I have lots of montis and they're my favorites.
