I have been dabbling in AP for a little over a year now and loving every minute of it. I started with a small system made from IBCs and have now built a larger grow house with three FTs and multiple GBs. I began using goldfish and quickly changed to tilapia. I now have approximately 150 tilapia in two 250 gallon tanks and am expanding the system with another FT and two more large grow beds. I also have an in ground pond with two females and one male tilapia that has been producing offspring rather quickly. I have attached some photos of the before and after. I would one day like to grow into a commercial operation and produce enough for my family and enough extra to sell to the public.
