I always tend to over think on plumbing to the sump and the return. I want to keep it as simple as possible. I'm thinking soft plumbing. My return pump is a jabeo DC pump. But once again I find myself over thinking the whole process. I don't want alot of pvc. Tubing is the easiest for me to deal with. Suggestions. The drain to sump should I run the lines into each other using a y fitting and into one hose or keep them separate? Then the return pump in thinking something like I have right now on my current tank. Pics to come.
