Does anyone know how to make a drain line stop "gurgling?" I have a "T" outside of the tank-one going down to sump and the other slightly going up with a cap that has a hole drilled in it-any solutions?
I had to make the hole bigger. I had the gurgle / flushing toilet sound too. I only have a problem when the salt creep fills up the hole and I have to pour a little water in it to clear it out and then I'm good.
yeap..you adjust it so that just the right amount of air flows in to the pipe thus reducing the gurgle..this way you can drain all the water you want..
Getting to the base of the problem... why do you need the MAX flow through the pipe? Generally speaking it is not good to max out a pipes flow in an aquarium.
