Additional Information

Precautions

• Use a drip loop: Route the power cord so it dips below the outlet letting water drip off before reaching the plug.
• Avoid large adjustments: Making big temperature changes at once may harm fish and other aquarium inhabitants, so adjust slowly.
• Maintain water level: Keep aquarium water above the heater's marked minimum level at all times while it is running.
• Check suction cup placement: Make sure both suction cups stay firmly attached so the heater cannot shift or tilt out of water.

Q2: How do I know which wattage heater to buy?

Q3: Can this heater be used in a saltwater tank?

Ans: Yes, the heater is fully submersible and built for use in both freshwater and saltwater aquariums. Its shatterproof housing and electronic thermostat perform reliably across tank types, making it a suitable choice whichever kind of aquatic setup you maintain.

Q4: What happens if the heater tips over or is out of the water?

Ans: The heater has a built-in auto shut-off feature. If it tilts so the top drops below the bottom, or is removed from the tank, it automatically powers down. Once it is repositioned and cools or is resubmerged, it resets and resumes normal operation.

Ans: The Aqueon Adjustable PRO Heater comes with a limited lifetime warranty that covers manufacturing defects. This provides fish keepers with long-term assurance of the heater's quality and performance, and Aqueon's support team is ready to assist with any warranty questions or product guidance.

Q6: Can I use this heater in a small tank, like under 10 gallons?

Ans: Yes. The 50-watt Aqueon Adjustable PRO Heater is suitable for aquariums ranging from 5 to 20 gallons. For tanks smaller than 10 gallons, the 50-watt model delivers consistent heat without stressing the unit or overheating the water.

Q7: How do I know if the heater is working correctly?

Ans: The built-in LED lights up red whenever the heater is actively warming your aquarium, giving you a simple visual check. If the light never turns on, or the water temperature does not rise toward your setting after a day, check the power connection or setting.
