ok i have a 72" t-5 fixture that holds 12 bulbs, i have searched for a thread that has 12 bulb combo but could'nt find one so i will ask, what would you use? I had lumiarc 400w 20k originally but had to change due to heat issues. I like the blue colors but i really want to get the color pop from my sps. This is a sps and zoa tank. It came with 10ks and 420's so i have them to use and i changed out 3 of them to ati blue plus so far so i have these to work with plus any others you might suggest for a combo. Thanks for any help
