Pond pump for pool?

[koiboiohio]

For some reason I can't find the catalog I was looking in but just doing a quick search online I found the Performance Pro Artesian2 ModelA2-1/2-C. 1/2 HP 3450 rpm 3.3 amps @6660 gph. Most pond pumps that I have found run way cheaper than pool pumps I'm just not sure if the flow is good enough for a high rate sand filter. Not sure how to post links but I found it @ Koi Market.com.

Pond pump output pressure is generally way too low to drive the water through a filter. Better check the pump curves, before you pull the trigger!
