How can I quiet down my pre-filter in a wet-dry filter?

I have an CPR overflow and it came with a tube and o-ring to seal around it. the drain pipe has a hole and the tube slides down into the flow pipe that goes into the sump. It adjusts by sliding the tube up or down to find the quitest position.
