Sump building

[telamont]

I want to build a sump from tap plastics. Im wondering how thick the pieces need to be and assume I will need a brice in-between because of how large this will be. I was shooting for 340 gallons with the tank being 72"x30"x36"tall. Thanks for the help!

A 340 gal sump? How big a tank you running? From sump size you must have a tank around 700gal.

You could prolly go 3/8" and be good considering the baffles and such will be your main bracing
