Jeremy,
Things are doing GREAT! I have learned a few things though. With the ATI 8' fixtures running 6 lamps each (since having 2 lamps removed each for this mod), I need very little LED supplementation. Secondly, although the BlueFish controller is nice (especially being wireless), it doesn't ramp from 0 and back down as smoothly as my previous build using the Coralux Storm X controller. The BlueFish has a tendency to flicker allot upon initial power and again when getting close back down to zero. The Coralux did not. I wish I would have just figured out a way to retrofit the Coralux now. Secondly, the Coralux really provides plenty of control in a simplistic way. The BlueFish's is much more tedious and complex. Not impossible, but you do have to give it much more thought.
As far as SPS growth, I'm more than ecstatic. Things that were not doing so well under just LED have transformed into colors and the proper shapes I had originally hoped for. Part of that though is due to nutrient content, which I'm now having to supplement NO3. I feed pretty heavy, but my NO3 levels were always near undetectable. I attribute much of this to my ATS. Since supplementing NO3, my LPS are regaining their happy spirit and the SPS have colored up nicely.
Glad to hear you're about to pull the trigger again. Best of luck in your new endeavor.
