Yes lots of blue 3 watt cree leds and a few t5s. I have zoas and palys under different lights different tanks. The best coloration and growth so far seems to be under majority blue lights. I also have been using 20k metal halide and rb cree leds and they are loving it. My son is running all blue and purple leds and t5s and his zoas and palys are going crazy. Ridiculous colors. Every polyp he has put in his tank has increased coloration and has good growth.
This is the first time I've heard so many good things about blue light only for zoas. As far as I remember.
What T5s are you using? ATI Blue Plus is the only one I would bet for growth.
Even though they're supplementary lights.
I agree with the 20000K MHs, very good bulbs, but I'm not a fan of LEDs at all.
The colors under blue light are ridiculous, indeed. They look amazing because they are reflexion of the blue lights. That's all.
