Thanks everyone for your replies. I'm in Woodbridge, NJ, by the way. I usually go to PetSmart in Woodbridge or Petco in Edison. These are the only pet stores I know of in my area.
Since I am not really a DIY kind of person, I think I've made a decision to get the Coralife Aqualight with a 36w, 6700k bulb. (I would also have to get a glass canopy for this, right?)
Does this sound okay for a planted tank?
