    Still pending final test.

    Just to reiterate since I can't completely see what's going on from the bell siphon to the fish tank... make sure there is some added pipe in such a way that it does not allow the "exit pipe" to create a siphon all the way from the grow bed to the fish tank.

    Affnan style bell siphons seem to be the most reliable. A quick search will turn up lots of great info by him....

    A few pieces of straight PVC and 2 90 degree elbows makes a great siphon

    Re: Bell Siphon issues

    Flienlow and anyone else trying to use a Bell Siphon, I came so close to filling in my AP set up that I spent months building in the ground out of blocks and cement. I spent 3 week trying to get the Bell Siphon to work, before going to my own design. It's been working non-stop since Sept. ( No tweaking, adjusting, nothing ). Not sure why so many people keep pushing the Bell Siphon with all the problems that comes with it.

    Check out my post, Pipe Siphon by Apollo

    I made a mental note of this sign when I was attempting to get the Bell Siphon to work!

    I am using a 3d printed bell siphon Click image for larger version. 

Name:	Untitled.jpg 
Views:	60 
Size:	8.9 KB 
ID:	5054 Does humidity have any affect to how it's supposed to work? It works great for 2 or 3 days, but then it can't seem to break the flow. I've tried reducing the flow, it won't start. I increase flow, it won't break? Would a stone guard help? Any suggestions?
