I’m planning to build my very first aquaponics system, but haven’t decided on the exact details of how the system will flow. I’m still trying to figure out the difference between ‘ebb and flow’ and ‘flood and drain’. What I do know is that I had to build a bell siphon (or auto siphon) before I did anything else. I’ve watched dozens of videos on YouTube, and I still can’t belive something so simple could be so effective. I put together a rough prototype of what I think I want my system to look like and built my siphon for that size: a 10 gallon fish tank and a 7 gallon Rubbermaid tote. To my amazment, the siphon worked as advertised. Now, it’s time to see how well it does when the tub is full of media.
