T5 bulbs

My corals get enough light from my 4x55w T5 setup because they seem healthy and grow. However, a lot of them end up more purplish brown, because they don't have the intense light / UV radiation that burns them into growing the sunscreen (pigment). I was wondering if anyone has any experience with any bulbs (and ordering information) that would help?

I have the standard 2x 420 actinic, 2x 6,5k (I think stock whites were 6.5k, not 10k) setup. Does anyone have any suggestions for some more intense bulbs? No I can't afford LEDs and I don't want the heat of MH (I'm already fighting against a 300$ electricity bill caused by a 70's era POS AC unit).

I heard rumors of some 20k T5's, but haven't found ordering info anywhere.

B-Willz, I'm pretty sure it's your tank I'm remembering. What did you end up getting? I remember that had a pretty intense coloring (that bleached some corals for a while).

Thanks for any suggestions!

With a 4X54W setup my self I plan to install 3 ATI Blue+ and 1 ATI Purple + at the next bulb change (now I am running 2 ATI blue + 1 ATI aquablue special and 1 ATI antinic)

Ok, that was my second question. Does anyone carry ATI bulbs locally? From my research they seem to have the top PAR ratings and some colors I really want to try. Otherwise I can order from BRS or w/e.

My guess is you are running too far on either end of the spectrum with 420nm and 6500k. Coral coloration is also effected by nutrient levels. High will cause browning, Low will cause bleaching.

I have a new ATI Blue + and Aqua Medic 15000k lamp I wont be using since I got the new LEDs if you are interested. And a few lamps with low usage on them.

Don't have much. Mostly pink stuff like the uvl Actinic White and 75/25 and a couple GE's but I think they are the 3000K, not the 6500. All new lamps which I'll sell for 10 each. Have some Sfigiloi actinics too.
