How thick of acrylic for this

[Scoobaman17]

I am putting together a sump that will measure out to be 42"Wide x 15"Deep x 14"Tall. This will have three baffles in the tank roughly at every third of the sump. How thick does the acrylic need to be and do I need more bracing for the tank or will the baffles do that work for me? Thank you all!

3/8 is fine.. 2" perimieter flange...

I agree mine is 36x16x16 and is 1/4" but it has bracing, baffles, etc. to help w/stability - if I had it to again I would go 3/8".

I started mine today and used 3/8" mine will be 36X24X14 deep with no top brace.. That being said it will have numerous baffles and dividers throughout this will include a built in frag tank.
