This project will be a large spa surrounded by a hydroponic garden. I started this project a couple years ago with a waterfall and a Koi fish pond in my original design. I have since change my design with the acquiring of this large Jacuzzi from a friend of mine.    

The new design will still have a waterfall from the corner high point that will spill back into the spa. The hydroponic solution will have nothing to do with the waterfall and spa water.      

 The key to the hydro system is that the four inch PVC pipe that receives the nutrient solution has to be the lowest point in the garden. As you can see by the pictures. The pipe starts at the solution reservoir and circles around the spa to return back to the holding tank.  

The steps at the left will lead to the nutrient tank that will be enclosed under the waterfall. It will have an entrance at the back of the garden.
