WHY AN AIR PUMP? 
In your aquarium, with one of our air pumps, you can safely 
double the number of fish. Growth of fish and plants is stimu- 
lated noticably. Areation brings out more of the natural color 
and beauty of your finny pets. And in breeding, all important 
to heavy producers as the egg layers, the fry will be bred 
stronger and grow more rapidly.
