Octopus NWB 150

This is the skimmer I'm looking at. With that said would the Eshopps PF300 be a good overflow for it or would I need to jump up to the PF800 which I think might be to big.

Im not sure i understand? are you trying to run an overflow from the tank strait to your skimmer or is your skimmer in your sump?

the 150 is da bomb. but it needs to be in a sump

Maybe I am misunderstanding things. I thought the overflow went on back of the main tank, plumbed down to the sump, goes through the chambers, and then through the skimmer back into the main tank. Am I wrong on that thought pattern?

no the skimmer sits in the sump. Skimmer is not part of the water flow pattern...Think of it as a filter that filters the water. You need a return pump. That is what sends water back to tank.

Got it. So the overflow sends water down to the sump, goes through the baffles/fuge, into the skimmer, then out to the tank through a return pump. The skimmer pump just mixes the water and bubbles for the skimmer to work. I need a pump that works with a overflow that are about the same size or slightly larger. Thanks.

You can add a gate valve (don't use a ball valve, Gate valves have finner adjustment) to the return feed, so u can balance the return flow to the inlet flow if you need to.
