My rule of thumb is that the pump should be capable of turning the pond
capacity at least once per hour. More is better. I had a 90 gallon pond
with a 5-gallon homemade "Skippy" fed by a 300 gallon per hour pump that
worked great for years. I now have an 1800 gallon pond with a 2400 gallon
per hour pump operating a Savio waterfall with skimmer and all is well for
two years now.

Hello all, haven't been here in a while. Built my pond in 2000, it's
about 1000 gal. Everything went well, learned a bunch.

Well, SWMBO wants a bigger one, and I retire in a few months, so I suspect
this is to keep me off the streets. G Gonna be about 2500 gal, not a
Koi pond, just bait store GF, and a bunch of plants. GF get to fair size
if the herons do make it a Mcfish fast food.

My question is about a "Skippy" type filter, what gph feeds this type
filter? Old filters were in the pond. Want external. I read a 100 gal
Rubbermaid tub is good for 3000 gal. But how much to the input side,
50gph, 200gph?

Thanks
