The Superfish 150W Submersible Heater is designed to efficiently heat a 200-litre fish tank aquarium. With a power consumption of 150W, this heater is capable of maintaining a consistent temperature to provide a comfortable environment for your fish. Easy to use and submersible, this heater is a reliable choice for any aquarium setup. Brand new. I have it maybe 6 years but I never use it.
