George,
You have much more experience with HSB than me. My Pond filled up 6 weeks ago, and they still have not been seen back to feeders, nor have i caught one.
I have also noted a very small fish kill with some 2 inch bass washing up on shore. maybe 20-30 of them.
During the rain I saw some very small bass and small CNBG going over spillway, but i never witnessed my 14-16 inch HSB.
Any thoughts?
I'm thinking about getting another water chemistry soon.
