I am about to send this back. No matter what I do I cant stop the skimmer from ejecting bubbles from the return back into my sump, which in turn ends up in my tank. I had it on my temp system in the garage until I put water and rock in my dt. Then I moved it to my dt. When it was on my temp system it wasn't acting this way. No ejecting bubble.
What am I missing here? My water level is 9". Same as it was when I had it on my other system, Could it be because my DT is cycling?
