## Long description

The sera Heater with Thermostat 50 W, 18.5 cm (model SE-08710) is a compact aquarium heater designed to provide stable, continuous heating in small to medium aquaria. Its integrated thermostat allows setting and maintaining a target temperature suitable for tropical freshwater and marine setups. The heater’s protective outer casing and suction mounting enable secure placement inside the tank while minimising direct contact with fish and décor.
Advantages
This aquarium heater offers precise temperature control through an integrated adjustable thermostat, ensuring consistent water conditions. The 50 W power rating is appropriate for small to medium aquaria where gradual, reliable heating is required. A protective casing reduces the risk of direct heating elements contacting inhabitants, and the compact 18.5 cm length allows flexible positioning. The included suction mounting simplifies installation and helps keep the heater fixed in place.
Suitable for
Small tropical freshwater aquaria
Small marine or reef tanks requiring stable temperature
Quarantine or breeding tanks where controlled heating is needed
Supplemental heating in larger tanks with multiple heaters
Key specifications
Power: 50 W
Length: 18.5 cm
Integrated adjustable thermostat for target temperature control
Protective outer casing to reduce direct contact with heating element
Suction mounting for internal tank installation
Suitable for continuous operation in submerged conditions
How to use
Place the heater inside the aquarium fully submerged and secure it to the glass with the suction mount at a location with good water circulation, away from filter outflows to ensure even heat distribution. Adjust the thermostat to the desired temperature following the manufacturer’s marking on the control. Allow sufficient time for the water to reach and stabilise at the set temperature before introducing sensitive fish or performing temperature-sensitive procedures. Regularly check the heater for secure attachment and visible damage.
Usage recommendations
For reliable temperature control, pair the heater with an independent thermometer placed at the opposite side of the tank from the heater to verify uniform temperature. Avoid placing the heater where it may come into direct contact with rocks, hard décor, or bottom substrates to prevent damage to the protective casing. For tanks larger than recommended for a single 50 W unit, use additional heaters or a higher capacity heater to maintain stable conditions.
