It is unlikely that anybody is going to shell out the money for an actual water
sterilizer for the pond. Nor is it necessary.
My UV has its own itty bitty pump, a maxi 1000

this clears algae out of a 1600 gallon pond. I have a big pump for my veggie filter,
altho that too may be oversized but it gives a nice waterfall on the other end.
