Getting there! I would make sure bubbles arent constantly spilling over... Adjust it so they bubbles get 3/4 to the way to the top, maybe a little higher. Once it's there, you will start to get a nasty skimmate... Probably take a day or so to actually see it, but if it's properly skimming you should see some production when you wake up tomorrow...
