Um, simplify things by not messing with them!!! You've got a nice light setup, and a beautiful tank. Why mess with it? JMO, of course, but I guess I'm feeling lazy.
The frags are doing great. After their little bath and acclim., the polyps were extended within 20 minutes. Made for a long night though. Then the GFCI tripped at 12:30 last night, and twice this morning! I didn't swap it out last night because I had to turn off the breaker for the garage and had no light. I stayed home this morning to get everything back in order. New GFCI, plus I still want to tie in another circuit to the garage.
After installing the new outlet, I turned everything on, the heater, chiller, all pumps, etc. and turned the 3 MH's on at the same time. Guess what happened? Nope, didn't trip! Now maybe I can just sit back and enjoy the corals again!
