Hi all, I'm new to aquaponics and I have used an ibc cut in half to make 2 beds. 200L plastic drum for a radial flow filter and of course my fish pond.
I started out with 2 bell siphon but they didn't work, ran a few times then just stopped working and beds would just fill up
I saw on youtube a you siphon so built one of them and installed it and it worked so I thought, after a few fills and drains, there is still water coming through the pipe back into the pond so it is continuous draining and if left it stays in drain mode. I've tried adjusting the flow for the bed but didn't seem much difference. Any suggestions would be appreciated.
I do have a thought, since my you siphon is an external one  I'm thinking of connecting 2 elbows to the drain in the drain bed as I have just left that alone since it was a bell siphon at first. I'm thinking that the water just flows into the pipe and nothing really there to force it to suck in air. So a mini you siphon in the bed i guess. Any other thoughts please
