I just got a aquatic life submergable protien skimmer today. The bubles are near the top of the collection box and the water level is near the top of the cup too, Is this normal? When will the gunk start piling up? How often will I have to clean it? How much of a diffrence will there be in water clarity and water prams? How does the skimmer work? I am just curious so please answer my questions. Thanks!
