I have recently acquired a used 55g acrylic aquarium. Based on the info in
the FAQ, I'm thinking a 2x96 or 4x65 watt fixture would be sufficient for
what I need. the tank is approx. 48" x 12" x 20" High. Should I get a 36"
lamp or a 48"? Any special considerations since its an acrylic tank?
I was thinking I'd like to build a simple wood valance for the top just to
hide things, so if a 36" light would work then I could do that easily.
Thanks!
Tom
