I have a foot long airstone putting oxygen into mine. my waterfall drops only about
2 feet and I dont think it is good enough. If the water is streaming down a series
of rocks where is splashes, then maybe it is oxygenating well enough.
an airstone also moves water from the bottom to the top creating a circulation
pattern that brings the mulm up. it is a side benefit. Ingrid

I have a question. I have a water fall for my pond does that reoxgenate the
water?? Should I have more air directely into the pond? Its approximately
a 4' X 8' oval shaped pond about 3 feet deep in center. Just removed the
muck and now waiting for the water to become less green. Using a UV light
with a bioforce 500 filter.

Thanks for any suggestions.
