Backyard Aquaponics
A place to discuss aquaponics

Hi Everyone,
I would like to add a second growbed to my cut and flip backyard system, i am running the pump continuously with a bell syphon to flood and drain.
How do i go about plumbing the second grow bed to the existing system?

Split the pump flow and have the additional grow bed flood and drain into the same place. Which is what I would do. You can even use the same drain pipe just extend it. Make sure if you use a shared drain it has a breather port and flows down hill.

You can have one grow bed drain into another if you would like.

Awesome thanks, that gives me a better picture.

You might have troubles if your sump isn't large enough to catch all the water from both grow beds draining simultaneously (assuming you're using siphons in both). You can either drain one grow bed to the next (and then to the sump), put in a larger sump or switch to constant flood (no siphons but continuous 24/7 flow keeps the water aerated).
