if you dont want to spend like $50 on that moon lite, you can just go get a blue party light and take a small lamp and aim it at the tank, thats what i do, i use 2 of them to cover the whole tank, works very good and only cost me like $7.
The Custom Sealife Moonlight cost me $23 from my LFS.
Another cheap solution is to get one of those green glow nightlights from any homecenter. They cost about $3 and cast a nice glow on the tank. This is what I used before I bought the moonlight.
