Hey Steve
I have pfo HQI ballasts. quite a few people have posted, not this forum, that overdriven radiums turn alot whiter, almost a 12k or 13k. I wanted a little more blue, bring out more color in my corals, just dont want to take a dive with par, but i might not have a choice.
ah well, time for VHO actinics
