Well the specs say your pump runs at a little over 600gph with 4 feet of head pressure. I am running the atmann 3000 that came with my tank. I believe it runs at a little over 700gph with my head pressure. Right now I have a valve turning down the return flow to a little over 3/4 power so most of the flow in the tank comes from my mp10s. The 14hf would only give you 30 more gallons of flow per hour. I have read that the rule of thumb is only 8 to 10 times of total tank volume per hour, if that's the case we both have too much flow lol.
