A good heater and thermostat is a small expenditure that will more than pay for itself by the fish that didn’t 
die. Since most aquarium fatalities are caused by temperature fluctuations, a heater in cold weather is practically 
a must. Automatically controlled heaters are perhaps the greatest benefit ever devised for the tropical aquarium. 
For a healthy aquarium the water should be maintained at a temperature of at least 70° F. For spawning egg 
layers or nursing sick fish the temperature should be gradually raised to 80° or 85° F, 
NOTE: A heater without a thermostat is not automatic. It will operate continually as long as it is plugged in 
All Heaters are guaranteed for one year—except against glass breakage. 
We recommend the following size heaters for your aquariums: 
15 to 20 gallons, 75 watts 
20 to 30 gallons, 75 to 100 watts 
80 gallons, 125 watts or more 
We strongly advise using a thermostat and pilot light on all aquarium heaters; for safety and economy.
