Medium Siphon 4″ Media (new v2)
A bell siphon is an easy way to drain your grow bed in a flood and drain aquaponics system without using a timer to turn your pump on and off.
Small and compact
No more timer & longer pump life
Increased water aeration
How it works: Water is continuously pumped from fish tank into a grow bed. When the water level in the grow bed reaches the top of the bell siphon, the bell siphon starts, and the water drains back into the fish tank. This flood and drain cycle happens repeatedly without a timer to turn off the pump. This cycle helps aerate the water for the fish and the roots of the plant and prevents root rot. This is the coolest part about this system. It works solely on the physics principles of atmospheric pressure and vacuums!
Installation:To install the siphon, you need a 7/8 inch hole in your grow bed.
