I am looking to set up a Herbie drain system in my 80g tank. I have a built in overflow, that has 3 bulkheads.
I found this very informative website that explains what is needed and how it all works. (no problems there).
I see one bulkhead / drain pipe that has a strainer on it, goes directly down to the sump, which it passes through a valve to control flow.
the second bulkhead / drain line goes directly into sump as well, but with no valves / strainers.
since I have a third bulkhead / pipe, i do not know what to do with it, or where it's supposed to go.
Can anyone help?
