Pond pump help

[fishkeeper170]

I am planning on building an above ground pond that will be a little over a 1000 gallons using stacked concrete blocks with liner holding the water. Is it better to have one 1000 gph pump or 2 600 gph pumps?

You should turn the pond water volume 1X per hour minimum. A 1000gph pump with head loss will end up around 800gph.

Thanks for the help, so it needs to at least be a 1200 gph pump. Should I go with large pump or two smaller ones?

Filter design should dictate pump(s) needed. Also keep an eye out on amperage....determine the monthly energy cost before diving in.

Yeah the cost was why I was asking because if I get two smaller ones with gph that add up to the gph of the large pump it would be cheaper then getting the large pump.
