I tested and my calcium, mag and KH were a little low. Calcium was 380, mag 1275 and KH 7.9 so I dosed my Reef Fusion 2 part system. I waited 5 minutes between dosing the two solutions, but as soon as I poured in the part 2 (raises carbonate alkalinity) it looked like it instantly turned into milky crystals and I've had this stuff floating around in my tank ever since. What did I do wrong and how do I fix it?
