With an aquarium heater, you can be able to raise or lower the temperatures of your fish tank to appropriate levels, depending on the fish species that you have.

It is particularly important to have a water heater in your fish tank as the temperature changes have an effect on your fish. In most cases, the changes bring stress to the fish, and if this stress is persistent, then it can have fatal consequences. We need to remember that large water bodies such as lakes and seas have their temperatures relatively constant.

And one needs to note that while people in some countries will be dealing with low water temperatures, in other countries, people will dealing with high temperatures and will thus need aquarium water coolers for their fish to survive.

Things to consider when buying the best aquarium water heaters

Before you invest in a water heater, it is important to know a number of things that will determine which type of aquarium heater to buy. Below are some of the things to consider;

Size of the aquarium tank

The size of the aquarium tank is an important factor when deciding on which type of heater to buy. This is because if you have a large capacity aquarium tank, and then you buy a low capacity heater, then you might not be able to achieve the results that you had envisioned in the first place. At the same time, the size of the fish tank will help you understand the number of heaters to buy. If it is big, then you might want to buy more than one heater.

Salty or fresh water?

It is also important to consider the kind of water in which you are rearing the fish. Different water heaters work differently under different conditions. There are those that will work properly even when used in salty water, while others might not work. So as you plan, be sure to first know if your water tank is salty or not, and buy an appropriate aquarium heater.

Cost of the aquarium water heater

Fish tank heaters are priced differently, depending on their unique features and characteristics. For this reason, it is important for you to go for a heater that you can afford. If you just purchase a water heater without considering the cost of purchasing as well as maintenance, then you might find it hard budgeting for other aspects of the fish tank.

And apart from the purchase and maintenance costs, you also need to factor in the cost that will be associated with the power to operate the heater. You can choose to use propane, natural gas or electricity, but then these will not just come for free. You will have to pay. So as you purchase, be sure to factor in the source of the power that will be required to make the aquarium heaters operational.

Ease of installation

While most of the fish tanks are easy to install, there are those that will need some skills when installing them. This necessitates the need to consider how easy it is to install the heater.

The fish species that you are keeping

Not every water heater works for every fish species. While you buy a heater, you will need to keep in mind the kind of fish that you have. Conduct research to find out which fish tank heater is best for your fish species.

What are the various types of aquarium heaters?

In the market today, you will find various types of water heaters. This means that you need to know these types before you visit an aquarium heater store to buy one. Below are the common types of aquarium heaters;

The heater is made up of a coiled element which has been encased in a glass of toughened plastic tube. Also, these types of heaters have a LED light placed near them to help you know whether it is on or not. Experts say that this type of heater is better than the immersible one when it comes to keeping the fish tank at a more stable temperature.

2.      In-line aquarium heater

The inline aquarium heater is best when fitted between the sump and filter so that it can heat the water as it comes back to the fish tank. The heater is made of a plastic which is heatproof.

The inline aquarium heater is the best for those fish keepers who have large and aggressive fish that fight with equipment in the fish tank. But it is also important to note that these types of heaters are generally more expensive than any other aquarium heater type.

3.      The filter heater

This is a type of fish tank heater that comes with the filter. The filter is fitted with the heater so that as the water passed through it, it is also heated before it goes back to the tank. You can easily find this type of heaters when you buy either the canister or powder filters.

4.      Immersible aquarium heater

This type of heater is also known as a hanging aquarium heater. The name comes from the fact that the heater hangs over the top of the fish tank and sits in the water. These heaters come as a starter pack for beginners, as they are the most common water heaters for fish tanks.

It only provides basic heating, as it is not as efficient as the other aquarium heater types. They are not recommended for brackish or saltwater setups.

5.      Substrate heater

Honestly, these are not actually aquarium heaters as they are not independent. They come with other types of heaters and are in the form of wires that are then fixed onto the base of an aquarium. They were popularly used in planted tanks as the heating promotes gentle water movement that can stimulate the growth of roots. They are very expensive, thus not often used by fish keepers.

Its function is to check the temperature of water. Also, there is a digital display. This part remains outside the water, and its function is to display the temperature of the water in the fish tank. Its function is also to house the batteries of the thermometer.

Why is this type of thermometer split this way?

The reason why the two parts are separated is to ensure that the electrical part of the thermometer does not mix up with water. Therefore, the electrical part of the digital thermometer does not get wet. So, if you do not want a thermometer that does not permanently sit in the water, then this is the best one for you. You just add a probe to your tank when you want to check the temperature of the water in the aquarium and then remove it ones you are done.

i. Floating submersible thermometer

Floating submersible thermometerAs the name of the thermometer indicates, this type of thermometer floats on the surface of the water in your aquarium. This sounds great. Isn’t it? When the thermometer floats in the water, it takes up the least space. The problem with this is that it can spin with the slightest movement of water making it impossible to read the temperature of the water as you can only read it front on.

The other problem with this type of thermometer is that the filters of the thermometer can push it around until they get stuck in one corner of the tank. Also, when you have decorations or plants on your aquarium, you can’t be able to take the reading of the thermometer easily. So, the only thing to do when you want to take the reading of this type of thermometer is to take it with your hands which is not practical.

The problem with this type of thermometer is that it can be very hard to read especially when placed near the rear of the aquarium. But if you have a small aquarium, then you won’t get any problem reading from any point of the aquarium.  The other problem with this type of thermometer is that fish can easily hit it making it topple over forcing you to use your hands to make it stand upright again.
