I have 4 bulb over 15 gal 3 ati blueplus and 1 d&d 6000k. I have no comparison using other bulbs combination, but so far I think my combination give a good result for me, the brown monti is coloring up after a month, some sps start encrusting after 1+ week.
but I've losing the bright green color on one of my frag, atl pink polyp monti, it became a teal green color.. but the growth is amazing, just the color.. on the other frag, my green digitata color is became more bright... hmm.. maybe I'll moving him up a little bit from the bottom to the middle of the tank and see if the color come back.
