What bout a 4 bulb t5s? Or 6? Do they make a 24 inch tek or Sumtn ?
I know that ATI makes a 6 bulb and an 8 bulb 24" fixture, but they're pricey to set up over a frag tank. What type of coral do you plan on keeping in the tank?
When I was looking at Sanjay's site I came up with this combo. Efficiency vs cost vs color and overall growth. The limit is the large reflector but 24x24 dimentions you have should be fine. Of course i build my own LEDs so what do I know...
