Almost a year ago during a power failure I disconnected the chiller to run my power plant. When the power came back I forgot to connect the chiller. Temperature climbed to 95F for two days. My soft corals melted and must of my corals died! All fish survived. I decided to buy a new tank using my rock and some of the corals that made it! Three months before the crash I changed my lights from MH+ VHO's to Chinese leds, less heat. Now I am changing my leds to Hydras 26HD. I have now two of them, need one more.
