Its a fowler. I will never keep corals in this tank. I DO want a high rate of corraline growth though. The bulb is a coralife 10,000k super daylight bulb. The other bulbs are regular 65w power compacts, with one bulb actinic, one 50/50. The power compacts are brand new, but the other bulb was first used in 2003! I really want to replace it. In the fowler, I would just like to bring the color out of the fish and coraline as much as possible.
