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. We also sell a range of thermometers so you can keep your eye on the exact temperature of your water. There may be differences between the temperature set on the heater and the thermometer. Use the thermometer to adjust to the correct temperature. Digital thermometers are the most accurate.
