Diy Rimless built. Did I screw up?

So I just finished putting together a rimless Starphire tank with scs1200 silicone.
The dimensions are 70cm long x 45cm wide x 40cm tall.
According to various online sources I convinced myself that 6mm glass would be good enough. Now I have it filled nearly 80% and the front and back are starting to bow slightly and I am sketching out. I also wiped the glass and the water inside really started sloshing around.

So far there are no leaks but I am worried that one day it may pop apart or burst a seam.

Am I worrying too much?

Mine is 90x45x40cm I went with 10mm glass. I read that 8mm was recommended but I went to 10mm.

I think you are to thin for that size.

Maybe if it was a 45x45x40 cube you'd be safer.

I believe my Mr. Aqua 60x30x36cm rimless is 5mm thick. It might be 6mm but I used some old, un-calibrated callipers to check.

Most people in this hobby will overbuild for peace of mind. Especially for a tank or stand. If I were you, I'd consider getting thicker glass cut and rebuild, just to be safe. In the meantime, you could water test this tank for a few weeks to be certain and then make a judgement call.

I measured from outside to outside in the middle and it is only bowed roughly 1/16"

That doesn't seem too bad?

I wouldn't worry as long as you're confident in the build quality. If it's a clean silicone job, no reason that won't hold. The ADA tanks are 6mm, and the older ones used 5mm glass.

Yeah, but ADA makes their glass from ground chunks of prehistoric meteorites.

Starphire glass has a lower iron content than cheaper types of glass, that's why it's so clear. That also makes softer and easier to scratch or break. I would go with a minimum of 8mm to be safe. 6mm will hold just fine IF you never bump it or drop a rock in it or knock over a peace of driftwood when it is full. Can you be sure none of those things will ever happen?

Anecdotal... Low Iron glass isn't any weaker as far as I know and there is certainly no proof I can find, it may scratch easier, but I'm not even sure about that.
