New Sump
 

Okay I have a couple questions on my new sump that I am going to build.....I am gonna make it out of acrylic I just need to know what size acrylic I need to use.....I am thinking about 5ft long and 16" tall with water up to 10 or 12"...Their will be lots of baffels in it!!, So again what size acrylic do I need to use???

there's a kind of "rule of thumb" chart here. keep in mind it's considering you have a eurobrace, which you probably should have if you're building it out of acrylic, since acrylic bends WAY more than glass. plus it keeps back salt creep
