Here's what I'm thinking. CB Pets has a 30 cube with two overflows on it. They drilled two holes up top close to the water line. Each hole has a strainer, bulkhead and a standpipe going into the sump. There is very little "stuff" in the tank itself. Has anyone seen this. It looks very simple and seems to work very well. If it should ever leak, it wouldn't leak out much. Has anyone seen it? I know you have, Blake. Ideas??? I'm gonna take my tank to Aquatic Warehouse to get it drilled, so hopefully they can sell me some matching plumbing supplies. I have felt quite comfortable in that store. I will take them out of my classification with the "other" LFS.
