I had a power failure 2 weeks ago for several hours. All my corals recovered including SPS, but my cup coral will not extend its large polyps. It doesn't look like it will die but no extension of polyps. All my water parameters are fine and I have preformed a 15% H2O change. Tank has been stable for 2 to 3 years. I two part dose and have same dual MH 150s on the tank. Any suggestions?
