Missing center brace

My brother has a 72 gallon bowfront that needed to be resealed and he was having problems with it so he bought another 72 gallon - I checked it out today and the previous owner had cut the center brace off the tank. Is that going to cause problems? I would think that it would be crucial to have on a bowfront. Here's some pics - first one is his original tank with the brace - then the one with it cut out

You really shouldn't fill a tank if a brace has been removed BUT that's not to say it still wouldn't work. My 46 bowfronts braces sag a little bit and aren't showing any tension from being filled on either one. They don't seem to be doing anything support wise but it could he risky when considering 72 gallons of water on your floor

The guy he bought it from said he cut it out because it created a dead spot with his lighting and had it running for 5 years prior to selling it. I personally would be wary - my brother said he filled it and had water in it for 5 days with no leaks but I'm urging him to re sell this tank. This will be his first aquarium and I don't want it to end up being a horror story.

If he still has the old one perhaps he can remove the top brace from that one and silicone it onto the new one.

Touché - I didn't even think of that. He does have the other tank - I'll see if he wants to do that.

Apparently a hot knife is very helpful in melting and removing the silicone holding the brace in place.

If he doesn't want to cut the other tank, he should be able to get a new acrylic strip to glue in there as a replacement support.

I'm not sure that would work.

Imo the center braces are more there for whats resting ontop the tank (lights and tops) then actual structure integrity. Like I said none of my bowfront center braces seem to be taking any load from the tank walls just hangs there. So if it were me I would just add an acrylic strip like stated just to keep and top from bowing due to having to reach 4' end to end. Remember though this is an at your own risk kind of thing lol

The center brace on your tanks are there for a reason and should never be removed for any reason. In doing so can result in total tank failure. Your tank will start to bow out both front and back.

How the tank lasted for years and years without failure in my strong opinion was pure luck!

I wouldn't chance it. Think about all the time,money invested in your tank then think about your fish and top it off with ruining furniture,floors etc....

Not worth it. You may think there doing nothing but they are. They are a very important part of the tanks design.

If your fish aren't dieing and they're healthy and happy, don't change anything drastic. I'd call removing the center brace a drastic change and strongly advise not to change the structure of the tank.

From a physics perspective, that brace prevents the two walls (front and rear) of the tank from bowing out from each other and is absolutely essential on a tank larger than 30 gallons. Even with tempered glass, it still bends when water presses against it.

Again this is JMO for what it's worth.
