Whoops. I think my corals are growing, cuz my alk slipped to 5.9! I’m still just using Kalk through my top-off, but I need to start making a stronger brew. My corals are getting sizable and the approach of spring comes with more moisture, so I have less evaporation. I know I have a long time before Kalk through the top off won’t keep up because it worked in my old tank and I had 5X the SPS.
