That is really weird. The only thing I can think of is your salt. Either that, or your refractometer needs to be calibrated. If your salt has high alk and calc, water changes won't help. I try to maintain 1.026 sg, 8.3-8.6 dkh alk, and 440-460 calk.
I use the lights that came with the biocube, the LFS guy said they were great for a reef tank. I have my lights set to overlap, so my moon lights come on, then my sunrise, then full lighting with my blue lights, then to sunset and to moon set. I am trying to get the most out of my lights. My corals seem to be doing well, I have had my zoanthids a little over a week and have 4 new polyps already! Thank you!
