Lawrence,
Wow your tank has gone through a lot since I last read this thread.
Are all your LED's reefkoi's "evolution"? (so are you just running LED's no MH combo...)
I'm debating on the evolution vs. other LED. How are the controls on the Evolution LED? Built in Timer? Is it Dimmable?
Can I see a picture of your tank with the canopy open? I want to see how you mounted the LED lights. Do you have any pictures of your sump? Are you using any reactors? You got so some many nice toys. I only can imagine what your outlet looks like.
Good luck
Jason
