Those of you familiar with hydroponics would recognize the system built in this video as a simple flood and drain or ebb and flow unit. In fact, you could just use this system for hydroponics, just delete the fish out of the equation. That said, what is aquaponics? Remember when those lions were singing about the circle of life?
