FTS!

what kind of light do you use on your tank i am looking to keep corals in my 5 gal. but i need a better light?

Thats a Coralife mini aqualight. It has two nine watt compact fluorescent bulbs. One actinic 03 and one 10,000K daylight.

do u just set it on the actual tank or did u buy like legs or somn. for it b/c i dont have a clue what to do.

I just have it sitting on sheet of glass cut to fit the top of the tank.

Is that a 5.5 gallon?

Yup. AGA 5.5

Nice.
