Another question guys. I have an intex external pool pump for the 8' pool can I run the intake line over the top of my cement tank wall and down into the tank or better through the side about midway down? Or? Also should I run pipe down towards the bottom or just midway into the tank? I was hoping to get some water flow by putting the inlet on one end and the return from the GB's at the other end. I need to know because the wife decided I need to face the tank with rock so I need to make the hole now if it would be better to have it through the side. Thanks in advance...
