My crawdad overpopulated pond has no FA, but I think you are right that it would take so many that the water would stay murky. My pond had a FA outbreak the first year, but not since the crawdad population explosion.

It's a catch 22, for us and them...Crawdads keep the FA eaten and then muddy up the water. The muddy water reduces the likelihood that more FA will grow and the crawdads loose their food source. What's next? I'm not sure as I still have many, many crawdads, muddy waters, and no FA...3 years in.


Fish on!,
