Hello everyone..
I need to replace a pump for my mothers pond.. I can't remember what
the ratio is for turning over the water per hr. I.e. if she has a 200
gal pump do I need a 200 gph pump or something larger or smaller..
Thank you

I'm pretty excited.. I'm opening my pond in the next few days getting
ready for spring.. Im anxious to see how much they grew over the
winter..
