I don't know the gph rating of my pump but there is a LOT of water moving
over my falls. Both falls are no more than 12 or 14 inches high though. Doc
Johnson (koivet.com) wrote that generally speaking is you can hear your pond
gurgling from 10ft away then you should have enough aeration. I realize that
there are a lot of variables to consider, though. I'll be keeping a close
eye on the fishies from now on.

Thanks, Jacky

I'm exploring the idea of adding an aerator, as was recommended
by some contributors here, but I get conflicting information. First of
all,
the pond is 3 yrs old and the previous owner did not have a mechanical
aerator. There are two waterfalls that make some noise, and today
I'm adding a water spitter (which the previous owner did have).
The pond seemed to be doing just fine with proper maintenance and
no mechanical aerator, at least until this dunderhead took over.

The waterfalls act as an aerator, and with a spitter, you shouldn't
need more than that. Ensure there is enough turnover in the pond,
through the water fall.
