I've made some changes, so I thought I'd post an update. My controller became a rat's nest of wires and I blew a few of my home made drivers.
I put everything in a computer case, and I think I was able to organize it pretty well. I replaced my drivers with Steve's LED quad drivers. They use the same chip that I used, but on a much more compact board, so I had to sandwich them in between aluminum heat sinks. I mounted the heat sinks out of the top of the computer case so I wouldn't need to add any fans.
So far I am really happy with the Steve's LEDs drivers. They run strings of 8 blues, or 8 whites, or 6 violets. The only thing you have to watch out for is the voltage drop across the chip. It should be as close to 1/2 volt as possible. To do this, I use little voltage changers I bought from FastTech for $1.50 each. I could have just added another 24V power supply(one for each drivers), but that would have been extra heat and more congestion in the case.
As for lighting, I cleaned that up too. I am now running 24 neutral whites, 12 violets, and 40 royal blues. All phillips luxeons. Note that this is only 76 leds over a 220 and I don't seem to have any trouble growing corals. I plan on getting up to 106 LEDs, but I'm not in a rush. Before I added the violets, acros were growing, but not very colourful. Since adding them, they have coloured up. I've never had trouble with montipora, seriatapora, or LPSs.
Yesterday I visited Aquariums by design. I got an awesome blue/Teal mini maxi anemone for $16. This pic doesn't really do it justice:
And here are some tank update shots:
My bubble tip moved from the front to the back of the rock pile on the right. I had to move all my corals to the left when he did it. The pink millie I got from frag fest got stung and didn't survive. If it moves again, I'll have a green BTA for sale!
