What a tremendous account, Hal. Thanks a ton for sharing that. I am stocking tilapia in my 1/2 acre pond this coming spring and, based on your experience, am really anxious to see what they do. I had a pretty bad watermeal problem last year, followed closely by FA, and can't wait to see what they do. Compared to the cost of chemicals, if these babies do the work for me like they did for you, it'll be an annual experience for sure.
