I decided to try my 1st colt coral. Big and beautiful, yellow. Put him good flow as instructed on the bottom of the tank. Looked great for about a week, then started turning white. Now another week later, and he is mush and falling apart. I have the new Solaris lights and think maybe I had them set to high, plus my water temp was close to 83. So I have turned down the lights from 100% to 70% and put a fan on the sump. Water temp is down, ranging between 78.5 and 79.6 for the last several days. Is there any point in leaving what is left of him in the tank? It is mainly his base that has melted and then the branches just come off. I guess I was hoping that there may be a chance that some of the branches could root, or amy I just dreaming? ph 8.0, nitrates a little high, phosphate .20, alk/kh2.17/6.1, mg 1110, sg1.023. this was before I did a water change yesterday. will check all again today. I realize these are low, and have been bringing them up slowly, maybe to slow?
