Yes, if I go this route. I had originally planned to retro everything. It's kind of a convulted story. From the start, I've had a wooden "floating" (supported by two wooden columns) light canopy that Brian at Kingfish built for me when we set up the Elos. It has 2 x 400W MH and 2 x 54W T5s. The problem is, because the light canopy sits off the water only about 12 inches, I really can't get to the back part of the tank to doing anything with aquascaping, cleaning the sand, etc. This issue I have now with Nitrates has kind of pushed me over the edge. I want something I can completely access the tank with. I was originally planning on building an aluminum frame, and changing out the 400W Luminarc full reflectors with 250W Luminarc Mini reflectors, and having 4 - 6 either 54W or 80W T5s (2 or 3 front and back). The more I looked at it (aside for the weight factor, I need something I can hang from the ceiling to solve the access issue), it looks like the retro will cost over $1K. Then I went by Aquatek this weekend. Their display tank is looking awesome right now, due to according to Bruce, someone consistently using the Reef Refresh on it. Since I'm ramping up on the NeoZeo system right now (same thing really), I talked to Bruce and Steve about the fixture they had. It turns out that its a simple Sunlight Supply 2 X 250W - 2 X T5 fixture. I was thinking if they could get that kind of results with that fixture, why am I looking at spending over a $1K with the retrofit. A fixture would be the same or cheaper (depending on which fixture I ultimately got), much faster, and a lot less hassle.
