Acryllic sump


New Member
I am thinking about making a sump from .177 impact resistant plex. i need to know if this will be strong enough or will i need to reinforce the side . probably going to be 30 - 36 inches long, 10.5 inches wide and 16 inches deep. Also do i need to place any baffles inside. I had only planned to put a protien skimmer, and return pump for now( no wet/dry). the main tank is a 55 gal. Any suggestion?

I think you will have to go with thicker will bow and break at that thickness. I would put baffles in to keep bubbles from the skimmer getting back to the main tank.
Go with 1/4" acrylic or thicker.


There is a site where you can calculate the thickness that you will need. I don't know what it is, but it's available. NEVER guess.
