Here I got about 40 gallon acrylic sump with refugium area.
Dimension: 36Lx15Wx16H
Drilled for external pump. But you can close the valve and use internal pump.
$ 145
I was going to post mine for sale here, but I can't beat the deal above. It looks like 1/2" acrylic all around.....if so, the materials alone are worth more than the asking price.
Very nicely built at an awesome price!
