Ok heres the run down, I have two 250w mh 20k at the moment. They are at 7 months right now but I am kind of skeptical as the guy I bought them from wasnt exactly sure when he got his. Ive been paying alot of attention to peoples tanks recently with their mh choices and have decided to go 12k. I have coralvue pendants which include came with the coralvue ballast and lumenbright ballast. I think my tank it rather blue at this point and would love to get better growth. I have two vho super actinics which will wlso be changed fairly soon after the corals adapt to the 12 bulbs.

So my question is which se 12k bulb do you prefer and why?
