i have a 2000gal pond with no heater so i will be turning of my waterfall during the winter so the water is not cooled too much( as been advised in prev messages) i will be re-directing the water from the w/fall outlet into solvet weld pipe which will be positioned into the lower half of the pond which will enable me to leave my filteration and pump running. my question is as the waterfall is no longer running will there be anough oxygen for my koi. i have no air pump in the filters.
