A 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.

Your siphon will come with a View Window (optional) so you can see the siphon in action. We also include a cover to protect from algae buildup when you aren't viewing. Perfect for kids, kids at heart, and for diagnosing any problems with water flow through your siphon.
