The back bows too. I have been worried because we got the fish for my disabled son. He spends a good portion of his day sitting watching his fish less than 2 feet from the tank. It would kill him if it ruptured.From my experience when my center brace broke on my 190 and I noticed it had a bow...an hour later it became a 20 gallon.
This would worry me.
Check the back does it bow too?
How would I reinforce it? The 4 sides are sandwitched in between the top and bottom so adding an extra piece to the bottom and top doesn't affect the sides. The overflow box would have to be removed.Whoa...that is a LOT of bowing...I have seen it before, but not that dramatic. Could be the height...or it could be the material used. True cell cast acrylic is quite ridgid when properly sized. For a 480g 1" acrylic should be fine...and like was said earlier, the seams look okay. Keep an eye on it but really, if it fails it will be very spectacular and most likely without warning. Reinforcing the sides and bottom would bea fairly easy job and maybe something to consider down the road.

I emailed acrylic aquariums on the 4th and they never responded back. I emailed again right now to seeThat doesn't look normal. My fathers 900 gallon tank doesn't bow nor does his 500 gallon tank. At least 8 year old tanks.
I would be worried maybe talk to some tank builders and email them pictures and see what they say. It may be normal but if its not it can be a disaster. It can ruin your house if all the water comes out.
I heard that bracing is to add a top piece. There is already a top piece. When I look up "aquarium bracing the seams" all I see are center braces at the top but it already has a center brace at the top and it is covering the entire top not like aquariums where it is a middle brace inside the tank it is a huge piece set on top of the tank so I'm not sure how more bracing can be added. If you added another piece to the top it would just sit on top of the existing piece. It wouldn't touch the sides. Maybe there is a different kind of bracing I have not heard of before if so please enlighten me.Seriously?
Think about what you just said.
Think about what and where the acrylic is glued.
Think about those seams blowing apart and then you will understand what it means to brace. Not adding to the top or bottom....bracing the seams.
Is this for real or are you just being difficult?
