Rimless tank flex, how much is too much?

[ImaFlippinDolphin]

So here i am looking at 3/4" thick glass bowing...ok, I get waters heavy and the fact I got a couple mp40s pushing the front a bit, I get it...the mp40s are towards each end dialed down. The bow is in the middle....not on the ends So, tank size is 192 display (rsr900 3xl). Anybody else ever notice something similar?

Of course the bow is in the middle, that’s the way physics works LOL. How much is it bowing? My 48” long rimless frag tank is 24” wide at the ends and 24 3/8” wide at the mid length point. Means each panel is bowing by 3/16”. Deep Blue told me that was well within tolerance.

I attached a vid, I'll measure tomorrow. I just noticed it, mines 79" and the bow is obvious, just asking not trying to shame a manufacturer. Looking for similar experiences

You know it is too much if it breaks. Seriously i got no idea, but i have never had a tank that i was able to visibly notice a bowing. Maybe i just dont pay enough attention.

Looking for similar experiences For some reason the video did not show when I was using my phone, but I see it now. A bit of bowing on a rimless tank is normal. Please do measure, but from the video, looks fine to me.

Video did not show on my phone, but I see it now. Looks well within what i would judge to be normal. I would not worry.

I'm picking up what you're putting down, and I see what you mean. I ain't sweatin it though. Looks pretty normal.

Did you ever measure the amount of bowing?

Exact reason I won't get a rimless tank no matter how "safe" they are.

I was told by the manufacturer that up to 1/4” is ok, but I’m at 5/16” to 3/8” of deflection.
