Hey all, HN1 and I were able to pick up an acrylic sump cheap at a yard sale today. The person that used it before was using an external pump and there is a hole in the side. We have a Mag 9.5 pump that we want to run submerged. What is the best way to plug up the hole in the sump? Thanks for reading.
