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?

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?
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.
For a pond around 1000 gallons, I’d personally lean toward two 600 gph pumps instead of one 1000 gph pump.
The main reason is redundancy. If one pump fails, the other one is still moving water and providing some circulation and oxygen. With a single pump, a failure means everything stops until you notice and replace it. In outdoor ponds that can matter more than people think, especially in warm weather.
Running two pumps also gives you a bit more flexibility. You can split the flow between a filter and a small waterfall or fountain, or place them on opposite sides of the pond to avoid dead spots where debris settles.
The only trade-off is slightly more maintenance and power use, but for a pond your size it’s usually minor. Just make sure the combined flow rate isn’t too aggressive for your filtration setup.
One small tip: whatever route you go, try to pick a reliable model designed for continuous pond use. I’ve had good luck with some of the Best Pond Pumps From EasyPro because they tend to run pretty quietly and hold up well in outdoor setups.
Takeaway: two pumps = safer and more flexible, especially for a DIY block-and-liner pond like the one you’re building.

Personally I would always go one reliable eco pump. Yes -filter design will dictate size and how it is run to some extent ie. Positioning.
But buying one suitably sized eco pump will always be cheaper than buying two smaller pumps which add up to the correct gallonage and will be cheaper to run wattage wise.
Any concerns over the pump not running ie failing can be covered by buying a solar air pump to keep the pond oxygenated. And of course if the pump fails due to a power outage, having two pumps is not going to help you at all where a solar air pump will cover and buy you time to sort any eventuality.
