Disadvantages of an outlet skimmer: - no Advantages of an outlet skimmer: - removes protein film - if it draws in food it will throw it straight back into the water for the fish to eat - if it draws in shrimp or fry it will throw them straight back into the water where they can live - if it draws in leaves it will throw them straight back into the water where you can take them out - does not cause the filter to aerateAdjustable aerator included: The skimmer is made to feed air into the water at the same time. There is a slanted tube inside, which you turn to adjust the aeration capacity.
