Custom Build Rimless with slight bowing
 

Hey folks, I just built my first ever custom rimless, dimensions are 34"w x 20"d x 17"h with 6mm glass(wanted it to fit in a very precise location). Should be around 45 gallons. Anyways, just did its first water test to about an inch from the top and the glass is bowing a bit less than 1/4" in the mmiddle. Is this bowing acceptable toloerance, or should I do a center brace or euro bracing? Any help would be appreciated. Thanks!!

Glass bows make me so nervous. When I filled my 110 gallon with 900 lbs of water for the first time my legs felt weak. It just seems wrong to see 1/2" thick glass bend! I measured my tank, it is 1/4" wider at the centre than at the ends. My tank has an extra glass brace on the long edges at the bottom of the tank but none at the top. All the glass thickness charts say 6mm is the correct thickness for your tank dimensions, so I wouldn't worry about it. Personally I'm more worried about my seals than the glass.

Yes there seems to be a lot of posts and advice around regarding concern for the seams not so much the glass. I've order some pieces to eurobrace the top. So much for rimless but I don't want to chance flooding the main floor! I've put a stupid amount of hours into this build.

Scares the shit out of me but I'm not a glass expert.

I wouldn't trust it ll it can take is a bump to shake it man. Keep in mind the pressure is on the outer edges but this also puts more pressure on the front now
