New issue today, the fans won't turn on to cool one of the units. I'm not too concerned since I can get a clip on fan to cool it and the fans are "optional" according to the manual. All my corals are responding extremely well to the lights, so I might not need a third unit. I actually think I can keep more hard to keep corals that I couldn't with my halides. The corals I tried just burned under them.
The skimmer is hooked up and is breaking in. This thing is a beast and I love it. It makes a little more noise than my mp10's at full speed, but it is bearable.
All in all I'm pretty satisfied.
