Drilling Ocean Systems Wet Dry Filter.

[FranklinP]

The tank overflow is done however looking through my pump selection it seems that there is only one pump that seems to have substantial power. It is a basement sewage grinding type pump. I looked it up online and it has Stainless steel body and parts with resin impeller. It is a Goulds pump. So I am planning on putting in a stand pipe inside the wet dry that topped off at the water line mark. It would then gravity flow into a main sump. May make some sort of partition to have more sand bed/ critters. Then one pump could move the return water. There is about 4-5 ft head here too so I would like the bigger pump. I will pick up a 20 gallon tank for this I guess. OK does this sound good or not? Thanks.
