Aqua One Adjustable Glass Aquarium Heater – 55W
Set the perfect temperature for your fish with the Aqua One Adjustable Glass Aquarium Heater. This high-quality, economical 55W heater has an adjustable thermostat with easy-to-use temperature settings and an easy-to-read temperature guide, so you can dial in exactly the right warmth for your fish.
It's fully submersible with double insulation for safe, reliable operation. The built-in thermostat switches the heater on and off automatically to hold your chosen temperature, and the handy "on" indicator light shows you when it's heating. The automatic shut-off adds extra peace of mind.
It's ideal for aquariums up to 50 litres, including small community tanks, planted tanks, shrimp tanks and betta setups. It's suitable for both tropical freshwater and marine aquariums, and because it's adjustable, you can match the temperature to the needs of your particular species.
