I currently have 3 250w DE MH's- 2 on my 72 and 1 on my 58- all running 14k Phoenix bulbs. When I set my 120 up, I had planned on just using all 3 on it and that would be that . . . but I have someone who would trade a 400w Reefoptix light and ballast for my AquaMedic 250w . . . should I do it or would that be overkill? If I go that route, I would like to try a 6500k Iwasaki on the 400 and put 20k bulbs on the 250's (similiar to those who supplement VHO's with their Iwasaki's) How do ya'll think that would work out?
