Many aquarium fish prefer to have warm water to live comfortably in. Fish do not maintain their body temperature just like mammals will. They need to have the water at a warmer temperature than room temperature, specifically tropical fish. This is exactly why you'll want aquarium heaters to have the water at the most suitable temperature. You may quite possibly lose your fish in the event the water is too hot, or overly cold, which costs you hard earned cash.
There are lots of types of aquarium heaters that you may get, depending on what kind of aquarium setup you have got and that which you prefer. One type would be the immersible or hanging heater. This particular heater you hang from the back of your tank. This type of heater features a control that has to stay above the level of the water, and it may seem problematical from time to time. A lot of these heaters are usually around the lower end of the price scale. You can also find the submersible heaters.
Submersible fish tank heaters are available a variety of styles and are more expensive. The complete unit is sealed, meaning that it may go totally underwater. You can also get one of these kinds of heaters that is designed to go below the gravel on the bottom of an aquarium. These heaters are generally stable and give greater uniform heat as compared with different types of heaters. It's also possible to get smart heaters which are submersible. A smart heater operates just like a furnace in your house. You set it at a specific temperature and switch it on. The moment the heater detects when the water is too cold, it will heat up until eventually the water gets to the temperature you want.
Smart fish tank heaters supply the best overall heat for your tank. Even so, no matter what heater you own, it is also wise to be sure you have got a thermometer in the tank. You may get one which sticks on the side like a sticker, or perhaps one which is literally in the water on the inside of the tank. However, you will probably want to consider checking out the different aquarium thermometers so you are aware if heater is functional.
