Can't speak to comparison.

We have pump fed.
Pump in the bottom of the pond.
Three feeds up to barrels
Which then gravity feed the VF ponds.
Return gravity to pond
Total head about 4'

Works fine.


Thanks for that, but how often do you have to get in to clean the pump?


Similar set up to me. I've got a foul water pump with no prefilter so I
never clean the pump.
