MEKKAPROOutdoor Hummingbird Feeder Made from Glass, Hanging 5 Nectar Feeding Stations, Bright Red, Backyard Feeder

Is there supposed to be a gasket in between groove where the two bottom pieces fit together? Cant get nectar level near the flower.

How does the ant moat work? it fills w/nectar when i flip it over. does it use h2o somehow?

Does the base come apart to clean the inside?

Is the metal loop length adjustable?
