View Full Version : T5 bulb selection

02-11-2010, 10:45 PM
I'm putting 4 t5s over a lps frag tank. I'm more concerned with growth than a pleasing color to the eye. Any recommendations?

two 6500k
one actinic
one midrange 10k/12k

6500k are supposed to give more growth but with LPS, I think they grow more from heavy feeding than light intensity. Two 6500k might be a little much. Maybe I'd just use one 6500k and two midrange 10k/12k.

If your free this weekend swing by I have 4 Blue Plus, 1 GE 6500, 1 ATI Actinic all from Grim's recommendation

So is light not as important to lps then? I did ask Grimm for a bulb recommendation but I think his whole thing is really more color than growth. He knows the colors of all the bulbs and how they work with each other but I don't think he has spent any time with what grows corals the best.
