How to choose the right fish tank heater?

A fish tank heater is among the best tools to help give your fish the environment it deserves. If you want your fish to have a long healthier lifespan, you should try to copycat its natural habitat. Salt water and fresh water fish both do best in warm water that stays consistent. Angelfish is one example of tropical fish.

Cold water fish on the other side like Koi can survive without a heated tank. If the temperature in the tank is not well-managed, it can make a lot of fish vulnerable to certain kinds of diseases such as ich. Always pay close attention to the water temperature in your tank especially during season change.

Things to consider the most when choosing a fish tank heater

Avoid the cheapest fish tank heaters

When selecting a fish tank heater, don’t go for the cheapest one. We’ve all been there! We always get what we pay for. Yes, you may have saved money now, but in the long run, you would have to spend more. Cheaper brands have the tendency to break or malfunction in just a short period. Also, a lot of cheaper alternatives do not have an accurate heat setting. When it comes to your fish’s well-being, you need something that you can rely on. You should go for mid-priced heaters because they don’t fail to deliver and they don’t hurt my pocket. You can check here for some mid-priced heaters.

Select the one with most reliable thermostat controls

Most brands have reliable thermostat controls, and they have the ability to maintain a constant temperature without doing some adjustments all the time. Make sure you check on your fish tank heater from time to time so that you’ll know that it’s still working properly and of course, you want to ensure accuracy.

Invest in a nice thermometer that you can stick to the outside glass, so you’ll know that your heater is working properly. Avoid floating thermometers because they’re often harder to read. You also have to put an automatic thermostat that can respond to the temperature’s fluctuations.

The three types of fish tank heaters include:

  • Thermo Heater
  • Rod-type and the
  • Bottom Heater

The Thermo Heater is a heater and filter conveniently built into one device. What’s good about this heater is that the water is cleaned and warmed at the same time.

The Rod-type is attached vertically to the back wall of the tank and it can either be submersible or not. Read the user’s manual because it will tell you if you can submerse the heater or not.

The bottom heater comes with heat cables that are supposed to be situated on the bottom of the tank before the substrate is added. They are good for plant tanks, but they’re quite on the high-end side.

Importance of choosing the right fish heater

In choosing the best fish tank heater for your fish tank, comparing several heaters is something to consider. This will ensure that the right levels of heat are being emitted through the tank and that the heater will have several different settings to keep the water at the desired temperatures.

So, whether there is one fish in the tank or 30 fish in the tank, the right heater is going to offer the right gauge and temperature setting options. This will allow the right amount of heat to be supplied to the fish, and the proper temperature to be set. It will also ensure the proper levels of heat are present depending on the fish they own and keep in the tank.

The right heater is going to allow for several adjustment options. It will allow the owner of the tank to constantly change the settings as needed. So, finding a heater that has easy to use adjustment features is something to consider. Also, considering a heater that allows for easy temperature adjustment when needed should be considered when choosing a heater.

Making sure that the heater is large enough to offer the right levels of heat for the entire tank, is also something that has to be considered by the purchaser of the heater. This will ensure that the water will be at the right temperature at all times. Also, finding a heater that automatically adjusts when the water is too hot or cold, is something to look for in the heater that is going to be purchased for the tank.

No matter what kind of fish you keep, the right fish tank heater is going to ensure they are kept at the proper temperature settings.

This will keep the tank properly adjusted, and the fish comfortable at all times. Before buying a heater, consider all settings and specifications in that particular heater for your tank.

Setting up Your First Aquarium

There is a wide range of sizes and shapes of aquariums as well as a choice of glass or acrylic aquariums, so how do you choose the best aquarium for your home and for the fish you intend to keep? We have put together a guide to help you to choose the perfect aquarium.

Where to Locate Your Aquarium?

The first thing to decide before you make a purchase is the location for your new aquarium. You must take account of the final weight of the aquarium when filled with water if you intend to place it on a shelf or table. A twenty gallon tank, once filled, will weigh about two hundred pounds! Do you need a stand or a specially designed cabinet?

Aquarium Size

Aquariums for the home come in a huge range of sizes from tiny glass bowls to huge five hundred gallon tanks. You will want an aquarium that is the right size for your home and for your fish. The first thing to consider is the location you intend for the aquarium. Measure the area to ensure the aquarium you choose will fit.

One thing to consider is that a bigger aquarium requires less maintenance. Small aquariums are much harder to keep the water balance correct, are easy to overcrowd and rotting food or vegetation can have an immediate affect on the health of the fish. A good size for a beginner is between twenty and thirty gallons. Decide how many fish you wish to keep. Very roughly you can keep one inch of fish to every gallon of water, but remember this is a rough estimate and a lot will depend on the type of fish and how well maintained the aquarium is. Always understock a tank rather than overstock!

The best way to choose the size of the tank is to purchase the biggest tank within your budget that will fit comfortably in the location you have chosen.

Aquarium Shapes

Since the introduction of acrylic aquarium, different shapes have been added to the traditional rectangular shape including cylinder, hexagon and round aquariums. There are also aquariums designed to be wall mounted and coffe table aquariums. Despite all these innovative designs the rectangular aquarium is still the best as the the area of water surface compared to the water volume is large which is important for allowing the exchange of gases with the air. Other shapes, with a smaller surface area compared to water volume, will often need more frequent water changes and more maintenance.

Do You Need a Glass or Acrylic Aquariums?

Both materials for aquariums have their advantages and disadvantages. The traditional glass aquarium is heavy and can spring leaks at the seams. Leaks are easy to fix however and usually only occur in an older aquarium. They are usually cheaper than acrylic aquariums. They only come in rectangular or square shapes.

The newer acrylic aquariums are lighter than glass and come in all sorts of innovative shapes. They rarely spring leaks as there are no seams. They are more expensive than glass aquariums but generally last longer. They are easy to scratch however so never clean with any kind of abrasive chemical or other chemicals which can fog the glass. Acrylic aquariums used to yellow with age but the newer materials stay clear throughout their lifetime.

There are a few basic pieces of aquarium equipment you need to include in your aquarium setup to make sure that your fish will thrive:


Filters are important to ensure the cleanliness of the water. A complete filtration system should have mechanical, chemical, and biological filtration. This way, not only visible dirt particles are removed but also other impurities such as toxins and odor are filtered out. You may achieve this by having one filter that performs all three functions. If you have a large tank, you will need at least two filters. Filters don’t need to be costly as there are inexpensive ones that are reliable and effective.


Another aquarium equipment you need to install are aquarium lights. These will replicate the lighting conditions in the natural habitat of the fish. Since the aquarium is often placed indoors, aquarium lights are the only means to simulate the 12 hours of daylight the fish need daily. This is so their behavioral cycles, like feeding and spawning, will remain normal. Note that insufficient lighting will cause poor growth, poor health, lessened coloration, and fish stress.


Fish are not capable of producing their own body heat, making them vulnerable to fluctuating temperature changes. As most aquarium fish come from tropical habitats, the water in the tank should be kept at above room temperature. For these reasons, it is important that you install a heater in your tank. Even as the temperature changes due to the weather or the passing of the seasons, your aquarium will maintain its ideal temperature with a heater.


While inexpensive, a thermometer is nevertheless an important aquarium equipment. A thermometer will provide you instant feedback for changes in temperature. There is a chance that temperature inside the aquarium is less than ideal. The thermometer will then tell you whether your heater is working properly or not.

Aquarium air pump

An air pump basically provides aeration inside your tank. This piece of aquarium equipment is needed since it increases water circulation to promote proper gas exchange. An air pump is also used to power aquarium equipment such as some types of filters and protein skimmers.


Lastly, you will need some aquarium ornaments. These pieces of aquarium equipment are not only decorative but are also there for practical reasons. They prevent fish from getting stressed by giving them a place to hide and rest.

In the case of aquarium plants, you have a choice between real and plastic. Most people prefer plastic plants since they don’t die and add to organic pollution. Live plants are also prone to being eaten and uprooted by the fish.
