Hello there fellow Reefer from Madison Wisconsin! I happen to stumble onto your tank build here on reef2reef, it looks like things were coming a long nicely till the power strip failure. Sorry to hear..why do these things happen only when your gone?!?! We'll just my 2 cents but I also did a retro fit t5 when I had my LEDs and I also used two Coral plus bulbs and in my option they looked great and increased my coral growth. Your problem is most likely that your corals were simply not acclimated to LEDs it literally took months before my corals started looking good again when I switched from all t5s to LEDs. Well regardless good luck on the new tank build I'd like to see it sometime!
