I had T-5s on my tank for the first 8 months or so and now have had 14K halides at about 6.5 watts per gallon since February. Several of my zoa colonies lost some of their more vibrant colors during the time that I had the T5s--blues and purples especially seem to have turned mostly green. I am assuming that the old lights were not enough to keep up those colors. Will the blues ever come back under these stronger lights or do they need like 20Ks or actinics to come back?
