48 inch 55? gallon hood questions

I can't see that it provides any structural support

Since the support is getting pulling tension it can be flimsy. Most makers make it strong so it is not accidently broken.
 
I used my first 55 gallon tank to house collared lizards when I was about 11. Every time I wanted to pick one up, they would run from one side of the tank to the other, and I would end up hitting my arm on the center brace. So after a few bruises and having my mouth washed out with soap, I finally took a hacksaw and removed it. After the lizards died, I decided to set up a freshwater tank. About a month after I first filled it with water it began to leak at the seams that when I noticed the glass bowing. I've always assumed this happened beacuse I removed an essential part to the structural integrity of the tank.

That is exactly what happened. I was given a tank and the center piece was broken so I thought no big deal just cut it out. Well it blew the seams. I repaired the tank and made a hood for it that I cut out U channels and slipped it over the sides of the tank. I then secured all four pieces together and it was solid for years and never leaked. That is untill an unfortunate accident that cracked the front glass... After a rapid water drain and fish rescue I went acrylic.

If you buy a one piece 48" hood for that tank, It will have relief cuts for the center brace. I own two such hoods and they fit on the tanks very nicely over the brace. Either way is fine, and 24" hoods are usually easier to aquire, but either will work. the real question is do you want 2 24" bulbs or one 48" buld. Once again the difference is trivial at best. in the long run one 48" would probably save you 2-3 bucks a year.

And I'm with RTR and Jericho absolutely don't add water to a 55 without the center brace.

48 inch bulbs being the most popular industry standard are by far the cheapest bulbs to buy for the length you get. in most cases 3 foot bulbs are far more expensive than 4 foot bulbs because of user demand & consumption. & i'm guessing that even the 2foot bulbs cost more & would be way less available & not have the variety color spectrums that the 4 foot bulbs have.

In my area 48" bulbs are marginally more expensive than 24" bulbs, but you are still at a two to one ratio each time you change bulbs, so the 48 would be cheaper in the long run. Hood price is another story. The last I checked and that has been a while, two 24" hoods priced out lower than a single 48" hood. But I do not recall if those hoods used 24" bulbs or 18" bulbs.

So a question about the centre brace. I have a (used)55 that didn't come with one. What is keeping that thing together? It is an older allglass model, and unless someone did a really nice fab job, it appears there never was one there.
 
Some of the older 55's Were built without the center brace, and glass thickness was engineered accordingly. I would contact all glass to get specs just to be sure. If it truly was built without a center brace (and not re-done that way by someone else) then it should be fine. I have owned 55's with and without the center brace, I do not remember the difference in glass thicknesses but do recall that there is one.

Thanks dave, I did notice the glass was a bit thicker than other 55's ive seen, but I forget what the difference is. This was a great help to me as I just moved into my new house and FINALLY get to set the darn thing up today!
 
Most 24-inch hoods use 18-inch 15watt bulbs.
...not a lot of light.

Someone mentioned using all-glass clear tops. That might look pretty cool. I did it with my 20gal tall tank and think I like it better than the opaque light hoods. And you can still put the 24-inch fixtures on top of it. Its different anyhow.
