I know on a Herbie drain the main drain pipe is supposed to be 1" below the water, but on my trigger sump the drain pipe goes into a bulkhead and then there is a pipe under the bulkhead that goes tot he bottom of the sump. Then the water flows back up and into the filter socks.
So I am trying to figure out why my tank is gurgling and I am thinking that has something to do with it?
Am I correct or is it something else that is causing the gurgling?
