Hi Cliff,

I also built a hood for a 55G tank and used 48" tubes, and although I know that
48" tubes can be a bit of a tight fit on a 48" tank like your 55G, there is
usually no problem getting them to fit.  Almost all of the commercially made
aquarium light fixtures for 55G tanks use 48" tubes.  In fact, the 48" wide tank
style, which includes the 55G, 70G, 75G, and 90G, among others, is one of the
most popular simply because of the fact that 48" fluorescent tubes fit so nicely
over it.  Another added benefit of the 48" long tube is that it is also the most
widely used size in commercial and industrial lighting fixtures, and therefore
is also the least expensive to purchase.  The 48" long tube also has the widest
variety of bulb types available.  If there is any way you can figure out how to
get a 48" tube to fit over your tank, I would recommend them as they are the
most cost effective to use. You might want to check out the "Krib"
(http://www.cco.caltech.edu/~aquaria/Krib/), as there are a few DIY hood
construction articles in the archives there that you might find helpful.
