I try to aim for 1 pond turn over per hour. After testing my 2500 GPH pump at 4' head the flow was reduced to 950GPH. My new pond is about 3000 G.

Do most people calcuate turn over rate on the pump rated GPH at no head or measure/calculate the GPH after head height and hose length to determine the pond turn over rate?

I'm realizing now I will likely need a lot more GPH or a dedicated water fall pump.

When you buy a new pump
you need to know how high you want to pump ,
And how many gph at that height..and buy one that fits your needs

problem was I kept digging after I bought the pump and the water fall got higher. I may end up buying a another pump, moving more water can't hurt and I think a backup pump for a larger pond makes sense anyway.

A back up is always good to have laying around
