MECHANICAL AQUARIUM EQUIPMENT 
The Controlled Aquarium 
T HOSE who make keeping fishes their hobby are not long con¬ 
tent to remain novices in scientific aquarium management. 
The aquarium offers more opportunities for the scientific exploi¬ 
tation of one’s hobby than any other household adjunct. In the 
aquarium there is life in the form of plant and living fishes. Con¬ 
trolling them according to scientific rule is a game which offers the 
challenge of a sport. The object of the game is to acquire a 
perfect balance of plant and fish life as this is necessary to keep 
both in the best of condition, to bring out the full color and beauty 
of the fish, and to have the conditions so natural that fish live, 
thrive and breed as they would in their natural habitat. 
But to accomplish all this is very often difficult because of such 
uncontrolled factors as light and heat. By employing the use of 
artificial light and heat, and with the aid of aeration, practically a 
perfect balance may be maintained without the usual precautions 
and methods necessary to accomplish this in other ways. 
Tricker’s mechanical equipment for controlling the aquarium 
eliminates all guess-work in aquarium care. It has been designed 
either in the Tricker laboratories or by associated experts. Through 
long experiments this equipment has been perfected and made 
available commercially at prices within the reach of everyone who 
wants to explore in this fascinating field.
