While most would get excited to go out on a Friday night, I instead stayed in and tinkered with my reefs. Reefkeeping needs attentiveness, and tonight was one of those nights where I needed to address specific needs, or lose corals.
Last time I tested the water in the frag system, Calcium was much too high, Magnesium wasn't where I wanted it, and Alkalinity was low. My dosing container had a bunch of white snow in the calcium section which didn't completely dissolve. Once Mg ran out, and Ca was nearly empty, I just had to wait for the alkalinity to be used up. The last couple of days, a couple of frags went south but I didn't put two and two together. All the alkalinity was gone.
