Answer: Yes, you can stock tilapia in Florida. Just keep in mind, tilapia is not going to get rid of the algae—the algae is persistent here in Florida. The water is hot, so algae’s always going to be there. If there was some way we could get rid of all the algae and it never come back, there would not be a pond management company. But yes, stocking the pond with tilapia will definitely help with your situation.
