I have to also say the Tilapia definatly eliminate FA. I put 24 good size Blue Tilapia into the pond basically covered with FA. Maybe it also died, maybe the areation helped to but within 1 week I saw a differnce I would say 3 weeks it was mostly gone.
My surface water was 46 in the morning yesterday, around noon I went looking for them. There still alive.... I saw a few sunning themselves. They got very big some look to be at least 2-3 pounds. I am wondering if the ground water is warm enough to get them threw the winter? I have read Blue Tilapia handle down to 48 degrees. That would be great.
