AquaParts 12″Bell Siphon with Media Guard:
An Aquaponics Bell Siphon is an elegant way to drain your grow bed in a flood and drain aquaponics system without using a timer to turn your pump on and off. By using this siphon will eliminate the cost of the time and the risk od timer failure. The siphon will help the pumps run continuously which results in longer pump life. Using a siphon to drain your beds will increase the aeration you deliver to your fish tank. The AquaParts 12″Bell Siphon with Media Guard provides an educational opportunity to teach students about partial vacuums, low pressure, pressure equalization, the impact of flow rates on siphon performance, and the force behind it all – gravity, as it is loaded with basic physics
(Note: The design of this siphon assumes 12″ of media depth. It will not work properly with more than 13″, and can be modified by shortening the stand pipe for beds with less than 11″ of media.)
Starting from the point of a drained grow bed, the grow bed will fill with water. When the water level reaches the top of the standpipe inside the Bell, water will start running through the siphon and out through the Drain Pipes and into your tank. Soon, the siphon will “fire”. At this point, the water in your grow bed will be rapidly drawn through the siphon and the water level in your grow bed will rapidly drop all the way to the base of your grow bed. When this happens, air will enter the Bell through the slits at the bottom of the bell, and the siphon will begin to “break”. When the siphon breaks, water will stop flowing through the Drain Pipes. Since the pump is running continuously, water will immediately begin to fill the grow bed and the cycle will repeat – indefinitely.
