I'm not sure how a Beckett works...is there an air intake to adjust? That skimmer isn't working very well. Even if there is nothing to skim (which there should be something in your tank because you have rock) the chamber should be totally white with bubbles. Maybe email your pic to the manufacturer and ask them go to get it working properly. As far as breaking in, I've never had a skimmer take more than an hour to produce foam, and not more than a week to produce a cup of green/brown skimmate.
