Aquarium Heaters & Chillers

A heater is essential to every tropical aquarium for keeping the water at a safe temperature for your fish. All heaters come with a variable control so you have set the required temperature of your aquarium, the heaters then use a thermostat to keep your aquarium water at the temperature you set. We also sell a range of thermometers so you can keep your eye on the exact temperature of your water.
