OK, let's see what I can answer...

Imzadi: For a 55g, Two rows of whites sounds like it would work just fine. However, if they are spaced too far apart, you will get two rows of white in your tank. If it were me, I would put the whites in the middle and the actinics on the sides.

RandalB: The buckpucks can handle anywhere from 5 to 32V. The number of LEDs you want to run will determine what voltage you want. For instance, with 12 volt, 3 is pretty much the limit. You could do 4 but they would be under-driven. Just consider that each LED will use 4 volts. It's only 3.6ish but use 4 when you calculate how much.

Looks like that was it for now. Like I said, I will have some pictures this weekend.

FYI: LEDsupply has sold out of the cool white Q4 LEDs that I used. They are going to be stocking the Q5 cool whites soon, though. They reach a higher K rating and have a higher output, as well. I may look into upgrading... already.

Thank you for all the positive replies and I hope to see any systems you guys build!
