What is an Automatic Bell Siphon and what is its purpose in aquaponics?

An Automatic Bell Siphon is a device used in flood and drain aquaponics to regulate the water levels in a grow bed. It works by automatically creating a siphon once the water reaches a certain height, allowing the water to drain out and then refill, repeating the flood and drain cycle.

Can I use the Automatic Bell Siphon for grow beds of varying sizes?

Yes, this bell siphon is suitable for grow beds between 200L and 1000L, with a depth of 220mm to 300mm.

How do I install an Automatic Bell Siphon in the grow bed?

To install the Automatic Bell Siphon, you need to drill a 30mm hole at the lowest point of your grow bed and follow the step-by-step guide included in the product package. The siphon comes with rubber seals and an outlet pipe tail for easy installation.

How do I choose the right size of Automatic Bell Siphon for my grow bed?

Select the size that matches the depth of the media in your grow bed. For instance, if you have a 300mm deep grow bed filled with 270mm of media, the 300mm bell siphon would be suitable. For a 270-300mm deep grow bed with 240mm of media, a 250mm Bell Siphon is perfect.

Is there a way to prevent debris from entering the Bell Siphon?
