lighting discussion would be great. i've looked at tons of various bulbs, spectrums, and all and have no idea what to buy. right now i'm running Iwasaki's 6500k 250w lights. little yellow for me but the polyps, clams and all seem to really like them. everything is more extended than in the past. i've also ran 10k bulbs and all. nice white light. i'm looking for something that has a little more blue but also has good coral growth, etc.
