How Fish Tank Heaters Work
February 18th, 2010 . by adminFish tank heaters are one of the essentials for your aquarium, especially if you plan on keeping tropical fish. There are also coldwater fish, and these kinds do not really need a heater.
The price range of most heaters can include pricey models, depending on the wattage. The usual rule is to have five watts for every gallon of water. If you have a large aquarium, then the ideal thing to do is install more than one heater, depending on what you need.
fish tank heaters work by maintaining a certain temperature for your tank. There are different types you can choose from, but all come with a thermostat, which should be attached outside the tank, and has a separate adjustable dial.
When you’ve installed your fish tank heater, just leave it on—no need to plug and unplug it when you leave the house. It works automatically, adjusting the temperature when needed.
