hi. I have a tank with sump filtration. The back overflow on my tank has a pvc pipe that the water flows down to my sump. Should my pipe be totally submerged? This is the setup the guy used that I got it from which is the reason I ask. Even with the ball valve open all the way I'm getting a lot of air flowing down? Should I cut a foot off the pvc pipe? Here's a pic and you can see the water line in my overflow.
