So, sometime I would like to get new T5 bulbs in my Aquaticlife fixture(4 bulbs). I'm not crazy about the stock bulbs! So, when I get the new bulbs from my LFS, they will probably be ATI's. I want the color in my tank to be more blue than it is now, but not TOO blue!! Also, I want my corals colors to come out a little more. I just don't know what kind of T5 bulbs would be best! Right now, what came with the fixture is 2 10K bulbs and 2 420/460 bulbs. I don't think I want to go back to a 10K bulb, more like a 12K. What do you guys think?:thumbs:
