Ok so I'm at it again!
Thinking of building a tank with sump, thinking
3 x 3 x 3 or 4 x 3 x 3 tho 3ft might be a bit on the deep side so that could be brought down to 2.5 ft

Is 8 mm glass going to be enough? Or should I be going 10mm?
Also thinking about bracing, what should I be doing bracing wise?

Also thinking of weirs.. .. should I be doing a double weir or single?

Neil,
Here's a link to Colin's article from a while back:

Somewhere he has another article which refers to weirs etc, I'll see can I find that as well.

HI
Minimum safe glass thickness for 3ft high tank is 13mm and that's with bracing. Brace less require at least 19mm(i wouldn't even consider brace less)
If 8mm is what you have, then max height can't exceed 40cm, that's braced as well. Also i wouldn't use 8mm for bottom of that size, unless u are absolutely certain the support is 100% flat.
Bracing wise as much as u can so combination of euro bracing and cross bracing. 3x3x3 is over 700l u don't want to have any issues with that kind of volume

Thanks John
Should have had a look there but never thought about it to be honest
