About Lifegard Aquatics Heaters

At Lifegard Aquatics, we manufacture two types of aquarium heaters: adjustable and preset.

The main difference between our heaters is that one is adjustable and the other is preset to 78° F, the ideal temperature for most tropical fish. Preset heaters are easier to use because they require no adjustment at all. This reduces the risk of under or overheating. While both heater styles are small, preset heaters are smaller, making them preferable for tiny pico tanks.

Here is a quick rundown on the similarities and differences between our two types of heaters:

Aquarium Heater Tips

• Good water circulation is going to help your heater do its job more effectively.
• Monitor your aquarium water temperature using a thermometer. We sell an award-winning digital thermometer to fit your  needs.
• Monitor the temperature of the room where your aquarium is located. Using your home’s built-in climate-control technology to automatically turn on fans or your air conditioner may be necessary to keep your tank safe during the summertime.
• Unplug your aquarium heater before removing it from the water. Our heaters permanently shut off if you remove them from the water while plugged in to prevent electrical accidents.

Heater Instructions

1. Attach the heater to your aquarium using the suction cup mounting brackets.
2. Aquarium water level must be up to Minimum Water Level Line indicated on the heater.
3. Wait 20-30 minutes for the thermostat to acclimate to water temperature.
4. Plug cord into power outlet. Make sure the cord has a drip loop.
5. Turn the Temperature Control Knob clockwise until the pilot light turns on.
6. Monitor the temperature closely with the aid of an aquarium thermometer until desired temperature is reached. Once the desired temperature is reached, turn the temperature control knob counterclockwise until the pilot light goes off. Verify temperature on a regular basis to ensure that the temperature is maintained.
7. For higher temperatures, turn the Temperature Control Knob clockwise until the pilot light illuminates.
8. For lower temperatures, simply turn the Temperature Control Knob counterclockwise in small increments and monitor with the aquarium thermometer.
9. Verify temperature setting regularly for the next 6 to 8 hours to ensure that the proper temperature is maintained.

CAUTION

Your aquarium heater must never be operated outside of the water. Before removing from the water, unplug and leave the heater in the water for 30 minutes. Allow the heater to cool. Be sure to unplug the heater during water changes or regular maintenance.
