General Reef Discussion
I just tested my tank this evening and my Alkalinity is 1dkh according to my API test! Actually the minute i put a drop in it goes yellow and then to blue. Is that even possible?
Corals look healthy, I use Kalk in my ATO and dose Alk/Calcium.
Calcium is at 400, Mag is at 1400, and PH 8.28...
