What to do with a jacuzzi that you don’t use…

And the answer is…
Turn it into a tilapia pond!
Here’s our jacuzzi with hydroponics beds over the top ready to be filled with bags of clay pellets.  The plan is to pump the fish water up to the plants, allowing the plants to clean the water, then flowing back into the fish pond.

We completed this project over a month ago and the fish have grown tremendously.  About 2 weeks after this first group, we purchased 10 or so more.  And since then, we have 2 or 3 new babies.  In 14 months or so, we will have dinner!
