FAQs

Can I use this heater in a 100-litre tank?

No, the 300W model is specifically designed for larger tanks up to 300 litres; it will likely overheat a 100-litre tank.

Does this heater include an automatic shut-off?

The heater is designed for continuous reliable operation; however, always unplug the device during water changes to protect the heating element.

Can this heater be placed horizontally?

Yes, as long as the heating element remains fully submerged at all times, it can be mounted horizontally or vertically.

How often should I clean the heater?

Perform a visual check for algae or mineral deposits during every routine water change and clean the glass tube as necessary.

Is this safe for saltwater aquariums?

Yes, the waterproof construction is suitable for both freshwater and marine environments.

Troubleshooting

Heater is plugged in but the indicator light is off

Check the power outlet functionality and ensure the plug is firmly seated; verify your home circuit breaker has not tripped.

Water temperature does not match the dial setting

Adjust the dial incrementally and allow 24 hours for the water to stabilize; use a separate aquarium thermometer to verify actual temperature.

Condensation inside the heater tube

If moisture appears inside the tube, discontinue use immediately as the seal may be compromised, and contact the manufacturer.

Setup, Compatibility & Care

To set up the heater, securely attach it to the glass using the provided suction cups while the unit is unplugged. Once positioned, submerge the unit completely and wait approximately 15 minutes before plugging it into the mains to allow the glass to reach ambient temperature, preventing potential thermal shock. For maintenance, gently wipe the glass tube with a soft cloth during water changes to remove algae or mineral buildup, ensuring efficient heat transfer. Never lift the heater out of the water while it is powered on.
