Do you need an aquarium heater?
Not all fish need a Best aquarium water heater, but many do. Coldwater fish, such as goldfish, thrive in cooler water temperatures, so they don’t need an aquarium heater unless you live in a very cold climate.
On the other hand, tropical fish and marine fish in general need the Best aquarium water heater to keep the water in the aquarium at a correct, constant temperature. When in doubt, do some research to find out the water temperature requirements for your fish (or the fish you plan to keep).
Some types of fish have very precise water temperature requirements; For them, just a few degrees can mean the difference between disease and health.
There are four main types of aquarium heaters available: tank-mounted, submersible, substrate, and filter.
These units, also called “necklace” heaters, hang from the back of the tank, partially submerged in water.
Tubular submersible aquarium heaters can typically be fully submerged in water.
Place “Under substrate terrarium heaters,” also known as “substrate” heaters or “heat string systems,” beneath the substrate (sand or clay) at the tank’s bottom.
Aquarium heaters are one of the most important pieces of equipment you can add to your home aquarium, but they are prone to failure. The vast majority of us aquarium hobbyists keep tropical fish that require warmer water temperatures, so an aquarium heater is a must.
There are numerous types of terrarium heaters on request and it’s veritably easy to buy a cheap terrarium heater and suppose you’re good to go. The Best aquarium water heater are not prone to fail, they are well-built and will safely heat your home aquariums. I will discuss what a full immersion heater is and also talk about the typical glass heater vs. the titanium heater. I’ll also talk about tank safety and how to avoid tank disaster if your aquarium heater fails (and it often does). Let’s Begin!
Advantages Of The Best Aquarium Water Heater
Since most of us in the fishing hobby keep tropical fish (marine fish), they need the water temperature range to always be around 75 to 80 degrees Fahrenheit (24 to 27 degrees Celsius). Since we keep our aquariums indoors, most people think that the ambient temperature in our home will keep our aquariums at a safe water temperature. But the seasons change and there are times, like winter, when the ambient temperature in your home or inside your home can drop below 70 degrees, endangering our precious livestock. They don’t tolerate temperature changes well.
The Best aquarium water heater not only maintains a high water temperature for tropical fish but also allows you to easily adjust the water to your desired temperature. They are also precise. Some have a separate temperature controller, providing redundancy in case of heating failure.
What we were looking for
It is not easy to find the Best aquarium water heater on the market. There are countless manufacturers in different price ranges. Filtering out the good from the bad is what we use in our criteria here.
The aquarium industry is filled with tons of cheap products, but this also means that the quality and reliability of the products can be questionable. It’s very easy to go to places like Amazon and find a cheap Chinese heater that will work on your tank. But they usually don’t have quality control and aren’t made to last.
There are places in the world where they raise tropical fish without having to worry about heating the water. These places are called “tropics”.
Choose a heater keeping tank water at 20-30°C, with 24°C adequate for typical tropical fish, meeting their preferences.
Keep in mind that even if you heat your home, an aquarium heater is usually necessary. Aquarium water needs stable warmth for optimal conditions, not just heat. Consistency matters to create an ideal environment.
Ignoring aquarium water temperature causes stress, health problems, and death, affecting all aspects, including plant life, and overall aquarium health. But while this is an important point to keep in mind, the solution is simple. Invest in an aquarium heater.
Buy/install a heater for precise tank water control, avoiding the temperature issues mentioned earlier. It’s a simple solution for optimal conditions.
Not many of us would like to live in an area with year-round temperatures. In some places, winter with very cold weather is inevitable.
Cold climates avoid low dissolved oxygen, but lower temps are still uncomfortable for fish and plants. Both face challenges. They bear great stress under low temperatures and death can be seen. So you can do something with this weather.
The aquarium heater is a simple, effective way to heat a tank directly. I’ll guide you in choosing the right terrarium heater.
Do you need a heater in your aquarium?
It depends on what kind of fish you are going to raise. Certain tropical fish undergo subtropical metamorphosis, adapting if the region’s temperature drops by 5 to 10 degrees.
The second reason is that the heater consumes a lot of energy. So you don’t pay a small energy bill on a large tank. Breeders raise water temperature by relocating the aquarium to a warmer spot or using devices like lights for control.
However, this will only work if the temperature around you is not too cold and the type of fish you are raising has a wide range of temperature tolerances. In many cases, you need a heater, which I explain below.
When do you need a water heater?
However, in some parts of the world, you have to deal with extreme cold. If you don’t do anything to heat the water for your fish, they may develop health problems and die.
You don’t want the temperature to change suddenly. The main use of an aquarium heater is to control the temperature of the tank at a set temperature. These heaters only turn on if the temperature is not at the right level.
Some species require a specific temperature to obtain a breakdown of the sex ratio of their offspring. Therefore, using a heater is very useful for extending their breeding period.
How To Choose The Best Aquarium Water Heater Companion
If the manufacturer gives the specific capacity in gallons/liters that the heater can heat to the exact temperature you want to reach, follow it.
If not, to keep it simple, as a general rule, you need 1 watt per 1 liter or 4 watts per gallon of water.
And if you still have room for a larger fireplace, you should get one larger than the base above, and another spare.
I’ll go into detail about backup heaters below.
It is better to use two small heaters than one large one.
As mentioned above, you need a heater that is larger than the usual norm (1 watt per 1 liter). So for that matter, I would have a double heater and another backup heater.
If you have two heaters, you can also turn one on if the other one is not working or no longer works.
So if I have a 100-gallon tank I will need 200-watt heaters. If one breaks, I still have a solid heater that still works fine.
You can also have more than one backup heater and not worry so much about adding multiple heaters to the tank. These heaters have a thermostat. So when the temperature reaches the level set on the heating thermostat, it will not turn on.
The average home user will likely choose an indoor or immersion heater based on their preferences.
With indoor heaters, the water flows continuously. Meanwhile, the way the hot water flows depends on where the immersion heater is placed: horizontally, vertically, on the sides, or centered on the bottom of the tub.
If you want to remove dirt from your tank for a neat and clean tank, choose the inline heater. This is a good option for smaller tanks, where you have trouble submerging the heater in the water.
In general, high-quality things do not have a low price. However, that doesn’t mean you can’t get a good stove at a bargain price. It also depends on your current needs: small or large aquarium, whether you are a serious user or a weekend user, sometimes the highest quality heating and the highest price just don’t make sense. This is why I also include several inexpensive products for hobby growers in this guide.
The best place to put the heater
Your science class taught you that warm water rises and cold water sinks. In this regard, the heater must be located in a place where it can distribute heat throughout the entire water tank.
Therefore, in a long and narrow tank, it is recommended to place the heater horizontally at the bottom so that hot water flows upwards.
In the short and wide tank, you should place the heater slanted so that the heater can be completely submerged and hot water is available in all areas.
Finally, if there is no water filter/flow, do not install the heater vertically and at angles/sides. This is because a situation like this makes it difficult for hot water to flow through the entire tank.
