Okay. I know you want pics...that has to wait for now. They are coming.

Another new system build. But I seem to have forgotten how to do some of this.

1/2 barrel on side, cut lengthwise. Stand pipe of bell syphon goes through the curved side as the media goes in the wheel barrow like hole. Now. What part keeps it from leaking? And don't tell me silicon cuz that isn't working. For whatever reason it doesn't stay stuck to the barrels and peels off after a few weeks. I can't find a uniseal for this either, they don't seem to work with two curved angles at 90 degrees. A compound curved angle of the barrel mating to the curved vertical angle of the pvc pipe is killing me.

I considered a constant flow syphon and I don't think I want that. Ebb and flow is the way to go for me. Right now though, all ebb, and no flow.

I used to know this, what am I forgetting please?

Thanks in advance.
