Having an aquarium adds beauty to your home especially when you have rare species of fish in your tank. You must maintain the temperature of your aquarium so that your fish will be comfortable and healthy. To do this, you'll need an aquarium heater.
Some fish rely on the water temperature so that they can maintain their internal body temperature. With an aquarium heater, you can keep the temperature in your tank at the level it should be. For example, tropical, freshwater and marine aquariums have temperatures between 22-30 °C.
Humans and other mammals are warm-blooded so we produce our own heat. As for fish, they are not capable of producing their own body heat. That is why an aquarium heater will prove to be useful for your tank especially when you have a variety of fish in your aquarium. If you are not familiar with how to choose the right aquarium heater, here are some useful tips.
You must know the type of heater that is best for your tank. There are four types of aquarium heaters: immersible heaters, submersible heaters, substrate heaters and filter heaters. Being familiar with each type of aquarium heater will make it easier for you to choose the right one.
Immersible heaters are often the cheapest. They must be above the water line which is one of the downsides to this kind of heater. It is not easy to set a proper temperature when using this type. What is attractive about this kind of heater is the low price.
Submersible heaters are more expensive than immersibles. The advantage of this type is that it can be fully submerged so that getting the right temperature is more effective. They cannot be easily repaired because the tube is sealed.
Substrate heaters are popular in Europe and with those who have live plants in their aquariums. This heater has heating cables that are installed in a substrate. They have the ability to heat the water uniformly. The hard part is that you have to tear down the tank in order to perform the installation.
The filter heater is the newest among all heater types. It has a heating block that can fit in the filter so the water that passes through it is heated. There is no need to place any equipment inside the tank, which is a huge benefit to those who prefer a minimalist looking tank.
Knowing the type of heater to buy for your aquarium is the first step. The next step is the heater size guide. You can find out the required size by subtracting the average temperature of the room with the temperature that you wish to maintain. Then you have to refer to the heater size guide to determine the best for your tank.
There are some more challenges in maintaining the temperature of your aquarium. During summer, the water in the aquarium rises so you may have to turn off the heater in order to keep your fish cool. During winter, you have to keep your fish warm and make sure your heater is working properly.
