Bulb recommendation..
I've got a 20gal tank with two 15watt bulbs on it (two separate light
fixtures), 1 powerglo and a sunglo.
Now, my LFS told me the best light setup would be to put two powerglo's in
there, what do you guys think? I need to replace both bulbs shortly and I
want to get it right the first time.
Phil..
