Amiracle skimmer

[d233]

I just hook up a Amiracle skimmer on my 72. It was a used skimmer and I took a chance. Whats happening is if I turn on the air it pumps bubbles into my tank. Right now the air is all the way off. I am running a MAG 7 pump on it. Do's anyone know what could be going on and maybe how to fix it. Please Help.
