Why Aeration & Aquarium Filters? 
The most important factor in maintaining an aquarium is 
"roper balance.’ This proper balance is sure to be main- 
tained when the water is aerated and filtered by means of 
mechanical circulation. Both aeration and filtration are de- 
pendent on air power for circulatiog. This air power is 
“furnished by an electrically powered air pump. As the water 
in your aquarium is passed through an aquarium filter it is 
cleaned, all impurities and dirt are removed, and freshly 
aerated water is returned to the aquarium. This means that 
your aquarium will remain crystal clear; instead of cleaning 
your whole aquarium, only the filter tank needs cleaning. 
The fish in your aquarium will be healthier and more color- 
ful, they will live longer, grow larger, and breed more 
prolifically. Depending on the size cf the pump, more than 
one aquarium can be filtered and aerated with a single air 
pump. Connections are made with plastic tubing, and special 
valves for the air outlets.
