Mass Denim

I think the tension on my bobbin is too loose?

I just recently got a Babylock denim pro from my grandmother and it worked fine when she sewed me a dress, but now any time I go to sew, the top part looks fine but when I turn it over there's MASS amounts of knotted hanging string. Is it the tension in my bobbin, and if so how do I correct it?

1. No, it is not the bobbin tension. Thread the machine with the presser foot up. When you thread with the foot down, the tension cannot function as it should and the thread flows through the needle without any control and you get looping stitches that LOOK like a bobbin malfunction.
