Animation Showing How Bell Siphon (or Auto Siphon) Works
A bell siphon is employed in ebb and circulation aquaponics and hydroponics systems to be able to control the circulation of water. Within an flow and ebb (also known as flood and drain) system water is pumped into the grow bed. At a specific point (usually 2 inches underneath the surface) the water drains through the bell siphon. Once the water hits the base you’ll hear the classic gurgle indicating the end of the drain phase. The process will then repeat itself over and over. The bell siphon is just this kind of essential element of any ebb and circulation system that getting it appropriate is essential.
