Aquariums can be a joy to children, fish-lovers, your visitors, and many other people. But when you’re setting up your aquarium, how do you know if you need a heater for your aquarium? There are several things that you should consider, including the type of fish you are hoping to keep as well as the temperature in the room they’ll reside in. Since fish are cold-blooded, they rely on the water around them to maintain their body temperature. So heaters can be crucial in keeping fish alive and healthy.

There are several types of heaters available, and they come in different sizes based on how large or small your aquarium is. The four main types of heaters are Immersible Heaters, Submersible Heaters, Substrate Heaters, and Filter Heaters.

• Immersible Heaters. These are often also called hang-on heaters and are the least expensive type of aquarium heater. Their biggest drawback is that the heater control must remain above the water line, causing setting the temperature properly to be more difficult.
• Submersible Heaters. These have the benefit of being fully submerged in the tank, readily concealed and easier to use when setting the temperature. However, they are also much more expensive than the Immersibles and are not easily repaired.
• Substrate Heaters. Among those who not only glory in the fish in their aquarium but also the plant growth taking place there, these heaters are excellent choices. They use cables to heat the water uniformly and are unnoticeable. The downsides are that they are more expensive, they are not as available in stores as the other previously mentioned heaters, and the whole tank must be taken apart in order to work on the heaters.
• Filter Heaters. These are the newest kinds of heaters and are made up of a heating block that fits into the filter, heating the water as it moves through the filter. Because it is unseen, it allows the tank to be more aesthetically pleasing. However, it is much more expensive and not easy to find and purchase.
