Hi, DR. REEF, the 2- 50/50's that you have now, are those half 12k, half actinic, or half 10k, and half actinic? I'm just learning about the bigger selection of vho bulbs. I love your reef, great actinic look. That's pretty much how I want my tank to look. Oh, and I see you have a couple hard corals, like bubble coral in the back, and montipora in the front, how do they do? Thanks, Ali
