    What thickness of acrylic do I need?

    My present sump is built out of plywood with a glass front. I came home and found the glass cracked so I have decided to replace the sump with one made of acrylic. My dimensions will be 48 inches long, 23.5 inches wide and 12.5 inches deep. This is a 60 gallon sump (unfilled). What thickness of acrylic do I need?

    Take a look at Melev's reef. The link goes to an 80g sump built with 1/4" acrylic.

    Poke around that site and you'll find a lot of info on building the sump.

    good luck!

    i agree, 1/4" will be fine but 3/8" wouldn't need and extra bracing. my sump is 48" x 18" x 16" and i used 1/4" ( with no bracing ) but i wouldn't go any bigger without going up to 3/8" acrylic. and if i hadn't run out of material i would have added bracing, i just got to greedy trying to make it as big as possible out of one sheet :b13:

    Sorry, I didn't notice your location a4twenty. But thanks for the cost estimate.

    My sump is about the same as yours will be and I used 1/4". I found through the middle areas where the baffles all are it was fine but at the ends where it is just and 18" wide piece with no brace it started to bow. I added 1" strips all around the top (basic eurobracing) and it is much stronger.

    I paid about the same as A4Twenty here in London for a 4x8 sheet of 1/4 cut to my specks.
