WHY AN AIR PUMP? 
The most important essential in maintaining an aquarium is ‘proper bal- 
ance.’ This proper balance is sure to be maintained when the water is 
aerated and filtered by means of mechanical circulation. As a result of 
this the air surface of the water is increased as well as moving the water 
within the aquarium. As the water passes through the filter it is cleaned, 
all impurities and dirt removed, and freshly aerated water is returned to 
the aquarium. This means that the fish in your aquarium will be healthier 
and more colorful, they will live longer, grow larger, and breed more 
prolifically.
