I installed my new reef octopus bh 100 yesterday. The directions weren't very good. They consisted of a diagram and nothing else. Since installing my aquarium has been filled with micro bubbles. I currently have no fish in it so I just have been letting it run but have had no change. I adjusted the collection cup several times but they bubbles are still coming. Anybody have this skimmer who can help? I've looked at a few videos online but can't get it figured out.
