Cecil, what about the PP in the pond a few years back??
OH yeah but it didn't kill them outright. Several came to the surface and I netted them. Could have made it but I netted them up just in case they went didn't and went to the bottom and died later. Turns out come spring I had about 25 that weren't effected a all.
Found out later PP is a bad idea in really hard water.
Still don't agree I've killed "a lot of fish."
