Remove Middle Tank Support Bar?

My tank is 48" long, and in the center of the black trim on top there is a black beam. This seems to be mainly used as a rest for the glass tops or a screen if using these. Since I am not using these, nor do I plan to be, I really would like to remove this.

Has anyone tried this? Did you have any side effects at all?


To me, it doesn't seem to be functioning really, it's quite loose and I would love nothing more right now than to take my hacksaw to it.

The tank is empty right now....so now is the time to do this.

Before you do that do one thing.

Take a 5 gallon bucket. Fill it full of water. Dump it on the floor. Now imagine what the contents of your tank will look like on the floor.

The company that built your tank put that brace in there for a reason. Most 4' long tanks have glass that is pretty thin. Without the brace it will bow. That will put stress on the seams.

I believe the brace is there as a safeguard, I don't know if I'd risk removing it, unless you wish to update your flooring soon....

ETA: Rex beat me to it!

I was a mechanical engineer for 2 years before I switched to CSE. The brace is there to keep the tank together (albeit a brace pulling the glass sides together against the pressure is not the best way to do it, it is the best looking way to do it).

go ahead..take it out and see what happens


the top of the aquarium will stretch out about an inch or two and creates a huge stress to the glass. this often results ina blow out

I'd not recommend it personally, but I do have a 4' long tank with no brace, and its 31" tall to boot. Probably its saving grace is that its 1/2" glass. I dont have it in actual operation yet, and I'll probably build a brace for it when its actually in my house but the person who had it before me had it for years with no brace.

I took the top brace off my 30 gal breeder,
but that's a really small tank, so I doubt
there is any danger with it at all.

I use to have a 150gal 6' tank the glass was 3/4" thick with no center brace but you sure could see the glass bow out when it was full.

gosh, that's scary. I'm surprised it was designed without a brace despite the glass thickness.

600 lbs of water is a lot of pressure on the glass. It would probably be better if there were braces pushing on the glass inwards, but that would make for an ugly tank, hend a brace pulling the sides together.

you could replace the brace with a clear piece of plexiglass. i've seen it done online several times. if your using one long bank of lights, it keeps the brace from casting a shadow and giving you a dark area in the middle.

you dont want to use plexiglass. its too suspetible to water making it warp. true acrylic or a piece of real glass would be just as easy

I have a 4' without a center brace. It's 3/4" glass, but still bows when full. I'm working on a canopy for it that will provide the support it needs.

I have another 4' that does have a center brace. The brace was 1/4" glass and broke one evening. The tank bowed out about an inch and I didn't have any way of repairing it at the time. I used a bright green ratchet strap. It seems to be working great... until I fix the problem.

Moral of the story, you need the center brace unless you have extra thick glass, which everyone has already told you. Also, if you do replace the ugly black bar with a piece of glass, make sure you get a reasonable thickness, the thin stuff just won't cut it.
