Well if your corraline algae is blooming dont worry about it. Make sure your skimmer is not clogged, but if there is a high ratio of bubbles to water inside the chamber you are all set. If the bubbles are in lower quantities maybe there is a broken spoke on your prop. As for my experience I could never get the "special propeller" to work and as soon as i put in the old prop the skimmer worked GREAT. Maybe your problem is with the skimmer. Its all about the fine bubbles in the chamber.
