Skimmer problem

[dustponds10]

Well I have an ASM G-1 skimmer and my problem is I just noticed that I have half of the bubbles going up the cylinder and the other half going out of the exit tube it is kind of wierd it has never done this before. Does any one know what I can do to fix the problem? I have taken it all apart to try to figure it out and couldnt see anything that would cause this. But if yo know please let meknow. Thanks
