I have the same light in my 29 gallon. I don't know a whole lot about lighting so you might wanna get some more feedback, but i like mine a lot. The only advice i would give you is to look into getting the coralife timer. It has 2 timers to control both bulbs, and when both lights are off, the lunar lights go on. only way to do that otherwise is to get 3 seperate timers.
