Yes- what's a little chlorine amongst friends ? grin I figured with almost a million gallons of water in the pond some water with a little chlorine in it was worth the risk for the aeration I was looking for. This is not the 12,000 gallons from the river - it is domestic supply for the house from same river but is treated at the plant before getting to the house. So today the pond got 12,000 gallons of river water and probably about 1000 gallons of the chlorinated via sprinkler.

Maybe not such a good idea ??
