Minimum glass thickness for rimless 30"X18"X13"?

[duganderson]

Looking at building a rimless NOT braced reef that is 30"X18"X13"? What is the minimum thickness glass you'd use of untempered glass?

I’m taking a guess here based on other builds I’ve read, but I’d say a minimum of 1/4 inch glass. Others will have better insight than me.

I'm may salvage some glass from a previous tank.....

The large 30X13 pans are 8mm thick NONtempered.
The smaller 18x13 sides are 6mm thick NONtempered
The bottom 30x18 is 5mm TEMPERED.

Do these seem like suffice thickness for this build?

You're good to go IMO.
