1. Powerful 300W – Suitable for medium-sized aquariums
With a power of 300 watts, this heater is ideal for aquariums with a capacity of 100 to 240 liters. Whether you have a community aquarium, a cichlid setup, or a saltwater aquarium, this power is perfectly adapted for most medium-sized tanks. The heater ensures fast and efficient heating and maintains a stable temperature, even in rooms exposed to temperature fluctuations.

2. Thickened Quartz Glass – Extra strong and durable
This aquarium heater is constructed from 2mm thickened quartz glass, which is a full 33% thicker than standard 1.5mm glass heaters. This makes it significantly stronger and more resistant to breakage, without compromising heat transfer efficiency. In addition, quartz glass is chemically inert and highly resistant to corrosion, making it ideal for long-term use in both freshwater and saltwater environments.

3. Precise thermostat with adjustable range (20–34°C)
The built-in thermostat allows you to easily set the temperature between 20°C and 34°C. Once set, the heater automatically maintains a constant temperature with an accuracy of ±2 degrees. The included thermometer decal can be attached to the outside of the aquarium, allowing you to check the current water temperature at a glance at any time. This ensures that your fish are always kept under optimal conditions.

4. Even heat distribution for stable performance
Thanks to its vertically distributed heating element design, heat is evenly dispersed into the surrounding water. This prevents localized overheating and ensures a stable, even temperature throughout the aquarium. Note: For optimal performance, it is important to ensure sufficient water circulation in the aquarium so that the heat can be distributed effectively. Ideally, place the heater near the filter outlet.

5. Easy installation with 3 strong suction cups
The heater comes with 3 powerful suction cups (including 1 spare) that allow you to easily mount it anywhere in the aquarium. Make sure the heater is fully submerged before turning it on. The suction cups hold the heater firmly in place, even in strong water currents. With a length of 26.5 cm and a 1.5-meter long power cable, it offers flexible placement options for most aquariums. And for your peace of mind: we offer a 24-month warranty on this product.
