I have developed two good acrylic sump plans as well as the bills of material. These are my own AutoCAD drawings that have been converted to .pdfs. I figured that there are individuals here who would like to use these plans for building a sump/fuge, and I'm offering them for use as public domain to people who use this forum. One of them is a design that I'm using for the sump on my new (to me) 90g reef tank.
Thanks.
