How does everyone out there plumb there return pump back into the tank? I have a few options and would like everyone's opinions on what works best and why. I have PVC
that enters the tank and is capped off at end with several drilled holes in it, or I have a piece that diffuses the water back out into the tank but it only will go a few inches under the surface of the water. It's shaped like a v where the water comes out and u can direct the flow. Any opinions or suggestions. Thanks.
