MARCO OUTSIDE FILTER—This filter operates efficiently and silently by 
means of an air pump—the same pump which is used to aerate the 
aquarium water. This filter works on the principle of siphoning water 
from the aquarium into the filter and then pumping it back into the 
aquarium. The water passes through a deep bed of carbon which acts as 
a fine filter medium, a gas absorber, decolorizer and general purifier. Next 
the water passes through a layer of special crystals which neutralize the 
acidity. The water is then returned to the aquarium crystal clear.
