Prizm Pro Crap

[Jaws]

Well, my lovely prizm pro seems to be acting up again. The chamber that fills with bubbles and empties into the collection cup is just filled with water right to the top. I barely have the flow turned up all the way and it's just filled with water. In the return chamber that empties back into the tank, I have a bag of chemipure. Since the bag of chemipure won't stay at the bottom of the chamber and continues to float to the top, which then causes some water to flow over the side of the chamber and on to the floor, I had to put a piece of rock on top of it to hold it down. I also have the air intake control turned as tight as it can go.

Are any of the things I'm doing contributing to why the skimmer isn't working properly?

Is there anything I should be doing to fix this problem?

I know getting rid of the skimmer is the best option but I need something to fix the problem right now.
