Everything You Need To Know About Aquarium Heaters

One of the essential equipment for tropical aquariums is an aquarium heater. Absence of this equipment becomes a matter of survival for the fish.

What is an Aquarium heater

It is a small device that works with electricity and maintains the temperature of the water in the tank. Aquarium heaters remain either fully or half submerged in the water of the tank; therefore, they are waterproof. There is a ‘minimal water line’ in these devices which tells how much part of it needs to be submerged.

Fully submersible aquarium heaters are more popular because they are safe. On the contrary, half submersible may create electricity leakage which may pose a danger.

Who needs an aquarium heater and why?

Tropical fish have a specific temperature requirement. Generally, the fish which are being used for aquariums are tropical in nature. It makes the aquarium heaters a must-have device in the tank. Moreover, if you are not living in a tropical area, you need to have an aquarium heater for the well-being and survival of your fish.

In the absence of an aquarium heater, the immune system of the fish weakens, and they might even freeze to death. Many fish get stressed and become less active in cold temperature.

What does an aquarium heater do?

As the name suggests, an aquarium heater warms up the water making it suitable for the fish. This device works on electricity and converts it into heat. When you switch on the heater, the water surrounding it gets warm and the temperature rises. Therefore, to make the device functional, it is essential to keep it in water with good circulation.

The aquarium heaters are designed in such a way that they automatically turn off as soon as the desired temperature is attained. Likewise, when the water gets cold, the device turns on to maintain the temperature all over again.

Things to consider while choosing an aquarium heater

  • They should be fully submersible

Fully submersible aquarium heaters are always safe and better than half-submersible. They do not pose any danger of electricity leakage and work effectively.

  • They should be adjustable

Aquarium heaters which are self-adjustable to the temperature are worthy than the non-adjustable ones. With them, you can set the desired temperature at where you want it to be.  Since they are more useful, they are pricier as well.

  • Get a high-quality aquarium heater

Aquarium heaters could be a one-time investment if you get a branded one which caters to all your needs. Installing a poor aquarium heater might lead to repairing or changing now and then.

  • Keep an account of the room temperature

You must note the room temperature when getting an aquarium heater because many times it is different from the outside temperature. It makes a significant difference in deciding the right device for your aquarium.

Also, since these heaters are automatic, they shut off when the targeted temperature is reached. Therefore, you don’t have to worry about the fish getting overheated.
