Cecil:
Interesting note you made about the fish die off near a well input. I'm thinking I should have this water tested and seee what's really in there. We did have 5 trout show up dead immediately in the vicinity of the well pump inlet (coldest area). I have no concerns with temp rise during areation through a medium as it is flowing so fast and cold- it would be no loss. It is likely due to low O2 at the least and aybe high nitrogen. While the flowing 1 1/2 pipe does hang 3 ft. above the pond and make quite a splash and churn, I would guess it is impossible that this same spalshing is oxygenating much of the incoming flow, since most of it is plunging 2-3 ft. below. Your thoughts on this?
