Yeah I was kinda curious about the pressure involved to filter the water through a typical cartridge. I know you can get different styles of cartridge that are more like a pleated pool filter style but I assume it would be no different and the flow from the drain would not be sufficient enough to properly flow.

By the way I found putting the prefilter on the the return just a waste of time.

I never thought of using the pressure from the return pump, but yea I can see how putting the prefilter on the return might seem to be a waste of time.
Thanks for all the input
