Why Do You Need A Heater

Fish do not produce their body heat, so they depend on the water temperature. Various types of fish will need a certain degree of water temperature. The heater helps you achieve and maintain optimal water temperature for your fish.

How To Choose The Right Aquarium Heater

With so many aquarium heater options in the market, it is easy to be overwhelmed. However, you can quickly narrow down your search by keeping certain factors at the back of your mind. The first thing you should consider is the type of fish you are keeping. The kind of fish will determine the temperature range of the heater you need.

Here are other factors to help you choose the right aquarium heater for you.

Size Of The Aquarium Heater

You need a heater that will efficiently heat and maintain the water in your aquarium. The rule of thumb in choosing the size of the heater you need is 2.5 to 5 watts per gallon of water. The bigger the aquarium, the bigger wattage heater you will need. 

You can use two heaters if your tank is enormous. Most home aquariums will require 150-watt aquarium heater, but sometimes it can be higher than that.

You also need a heater that will conveniently fit in the tank. Aquarium heaters come in all sort of size for the same wattage range. Getting something that will take minimal space in the tank and serve you conveniently can be a good idea. It gives your buddies more space to swim and enjoy.

Types Of Aquarium

Aquarium heaters contain vital information on which type of aquarium they are designed for. Although you can find a heater model that works for more than one kind of aquarium, it is essential to put into consideration the type of aquarium you have.

Reef tanks, turtle tanks, tropical fish tanks, and betta tanks have different needs. The best betta heater might not be the best reef heater. You will want to get something that is meant for your aquatic buddies.

Types Of Aquarium Heaters

There are several types of aquarium heaters. They are generally categorized by their installation method and type of material. These heaters work in various ways, and it is essential you know how each one functions. You need to maximize efficiency, and the type of heater you choose might make the difference.

Ease Of Maintenance

Heaters accumulate debris and dirt over time, which can be catastrophic to your fish if not removed in time. You may consider choosing a heater that you can easily uninstall and clean. You don’t want to incur maintenance cost, or installation cost each time you remove your heater for cleaning. Getting a heater that spare parts are readily available is also an advantage.

Your Budget

Knowing your budget also comes at the top of the list. With a wide variety of heaters in the market, you can get the right heater for you at an excellent bargain. Setting your budget will help you know what range of heaters are in your grasp. It is then easy to choose something that works for you without having to cry your way to the bank.

Personal Preference

To some people, style is everything because it defines them. You want to get something that will not make you want to rip apart the tank each ​time you look at it. There are a wide array of heater styles in the market. As long as your style does not affect the performance of the heater, you can always choose something that makes you smile.

What Makes A Heater Ideal For Your Aquarium

It is essential to consider the features that will make your heater more effective and efficient to use. Here are some features that might make a heater ideal for your aquarium:

Available watts

It can be an easy task to get a heater that will be ideal for you if you use the thumb rule of 2.5 to 5 watts per gallon of water. 20-gallon fish tank heater will need around 60 to 100 watts aquarium heater. If you take a 300-watt heater as a heater for 5-gallon tank, you might eat fish for dinner because that is too much power.

If your tank is too big, let’s say it needs a 400-watt heater, you can use two 200 watt aquarium heater.

Adjustable temperature

Some heaters come with defined temperature settings. At times you will need to adjust the temperature. You want to get a heater that you can easily change the aquarium temperature controller to favor your aquatic buddies. Just because you got a 500-watt heater does not mean that sometimes you will need to lower the power depending on the fish needs.

Access to controls

You don’t want your fish to have a panic attack just because your hand is all over the aquarium trying to locate adjustment knobs. Go for something that you can easily access the controls to make the adjustments you need.

Temperature readability

​Most of the heaters come with a temperature gauge. You will consider going for something more visible in water and easy to read. However, you can get the best aquarium thermometer from the market if your heater’s thermometer is not clear or accurate.

Tank size

​Your tank will also determine which heater is ideal for you. Small tanks may require invisible or small heaters. You don’t want half of your tank occupied by the heater.

Safety features

​We always emphasize on safety. If you have kids at home, you don’t want something that kids can pull out and start playing with. You should also consider getting a heater that has an automatic switch when the water is past or below the optimal temperature.

A light feature to indicate when the heater is on can also be an advantage.

Type of aquarium heater- Where should you place it

Now you know the factors and features to consider when buying an aquarium heater. We are going to look at the different types of heaters and where you should place them.

Hanging/Immersible heater

When you want an aquarium starter pack, then this is the type of heater that you will find. Immersible heaters are inexpensive but not the most efficient.

They are suitable for only small size aquariums. The heater is usually made from glass and does well in freshwater aquarium.

As the name suggests, the heater is placed at the back of the aquarium hanging. You will need to cut a small hole in the hood of your aquarium if it doesn’t have. It helps with holding the heater head.

Submersible

Submersible water heaters are completely submerged underwater, so no heat is lost. It is mostly made from glass which is susceptible to breakage. It can be dangerous if you have large fish. However, you can also find the heaters made from unbreakable material, but they will use more energy.

Submersible water heaters can be placed vertically or horizontally in the tank. You need to remember to give sufficient spacing between the heaters and gravel if the heater is made of glass.

In-filter

In-filter aquarium heaters are more convenient compared to submersible and immersible heaters. They do not require extra space because they are placed inside the filters. They work by warming up the water as it passes through the filter.

In-line

The in-line aquarium heater is commonly used in big aquariums or aquariums with aggressive types of fish. They are made from heatproof plastics which also acts as a safety feature. They are installed between the filters or sump.

In-sump

The in-sump heaters operate more like the in-line heaters. They are installed in the sump, which makes it easier to maintain as compared in-line heaters.

Substrate

We call them the invisible aquarium heaters because they cannot be seen in the tank. They are installed within the gravel. They function by heating the gravel, and the heat is transferred to the water. It has a thermostat which regulates the heat when the optimal temperature is reached.

How To Install An Aquarium Heater

Most modern aquarium heaters are easy to install and maintain. You will know if you need a single or multiple heaters depending on the size of your aquarium. The different types of heaters have different ways to install them. Here are general rules for installing an aquarium heater:

  • Check for any damages in the heater’s casing before installation.
  • Adjust the temperature and position the heater as recommended by the manufacturer or type of the heater.
  • Make sure there is enough spacing between gravel, plants, and decorations with the heater.
  • If you have an external thermometer, place it on the opposite side of the heater.
