Coralife Super Skimmer 125

Having some trouble with way too many bubbles coming from the "bubble-production diffuser cup" which sits in the tank. :help: How do I reduce the bubbles overflowing from the cup? Nothing in the manual about reducting the bubbles.
Thanks,
Mike

use the round red knob, tun it down, and the bubbles will turn down. the bubbles should only come up about 1/4 inch into the middle of the collection cup.
