It is essential to keep your fish at an appropriate place where light, noise, and temperature is suitable for your fish.
I did not have any idea about this initially when I brought my little fishy friends home.
But yes we learn from our mistakes and so did I.
As my fish family grew, I started taking care of these things more than ever.

What is an Aquarium Heater Controller?
Basically, an aquarium heater is a device used to warm the water in the aquarium.
Unlike humans and other mammals, fish don’t produce their own body heat. In that case, it is your responsibility to maintain the proper temperature of your aquarium.
If you own fish especially a tropical fish, then remember to buy the heater too.
Fish and Fish Tank Heater
The optimum temperature for your aquarium depends on what type of fish you own.
As one temperature doesn’t suit all types of fish.
Some fish fare better in a more warm temperature while some prefer a cooler environment.
So it is important to KNOW YOUR FISH.
Do proper research, and if you are keeping only one kind of fish then maintain the temperature which your fish requires.
If you are a hard core fish lover and have different kinds of fish in one aquarium, then the temperature for that aquarium should be around 80°F which suits almost all fish
But again, try your best not to keep different types of fish in the same tank if you cannot handle it properly
Types of Aquarium Heaters
There are four types of heaters for aquarium
1. Submersible heaters
2. Immersible heaters
3. Substrate heaters
4. Filter heaters

The knob or rotatory can help you set the desired temperature

Fish Tank Size and Heater
Although you require a heater and the temperature that is appropriate depends on the fish you own
The size of your fish tank is also relevant while buying a heater.
There are different sizes of heater available for different gallons of fish tanks
Importance of a Heater
Cold water can bring as much disaster to your fish tank as very hot water would.
The sudden change in temperature can be problematic to a very large extent.
As winter approaches the temperature of your house drops.
Similarly the temperature of the aquarium also drops which can be dangerous for your fish family.
There are some heating challenges that you would have to deal with, like heater breakage
In summer months you have to take totally opposite preventive measures due to the high temperature of water.
For better results I will suggest you to place the heater near the water inlet or outlet or in other words place the heater where there is more water flow than other areas.
Monitor the Temperature
After installation setting of the heater, you have to watch the temperature. It can take a few hours to 48 hours to give the desired temperature.
Increase the temperature of the heater if the temperature of the water is not raising
Lower the heat if it’s increasing the water temperature too much
YOU HAVE TO BE ATTENTIVE.
Some heaters have simple adjustments like warm and cold.
In that case, you have to warm the water until it is done or vice versa
While others have degrees, you can just set the desired temperature and it will either increase or decrease the temperature of your aquarium to reach the set temperature.
Appropriate Temperature For Different Fish.
Tropical fish generally survive in warm water.
For them a heater is important, especially in winters otherwise they will die in the cold water
The best part about most heaters is that they turn off automatically when the desired temperature is obtained
The temperature of water for tropical fish should be at least above 74 degrees Fahrenheit.
While on the other hand, non-tropical fish can survive in cold water
So if you are a beginner and don’t want a heater.
Then go for fish which can survive in room temperature water like gold fish
Goldfish can handle colder temperature.
Different fish species and preferable temperature
|Lake trout||53 °F|
|Rainbow trout||55 °F|
|Pink salmon||55 °F|
|Brown trout||60 °F|
|Yellow perch||64 °F|
What to Do In Hot Weather?
Cold water can be dangerous to your health.
In the same way, hot water can be hazardous for the fish.
Here are some tips to keep your fish safe.
In hot weather, increase the water flow.
At high temperatures, fish require more oxygen.
So moving water picks up more oxygen and the water cools as well.
Similarly to lower the water temperature, remove the aquarium head and bring a fan close to the water surface.
Some of the water will evaporate.
Now add some cold water as a replacement of evaporated water.
Keep in mind you have to add just a little amount of cold water, or else you will shock your fish.
Secondly, you can freeze plastic bottles and keep it in tank.
This technique helps a lot
Don’t keep a big bottle because that will change the temperature very quickly and such quick temperature change can be very much dangerous and harmful for your fish.
If you have placed the aquarium at a place where the temperature is mostly high, then you will need a chiller for the fish tank
Some of them can be placed directly inside the aquarium like coils
While some are placed outside the aquarium.
It works in a simple way
Water flows from aquarium through the chiller and then back to the aquarium
SOME IMPORTANT POINTS
For better understanding do read the instructions properly
When purchasing a heater check the thermometer, especially if you are buying a used one.
Though most of the heaters are waterproof because they are fully submersible, some are not.
So you should take care of the heater or to be on the safe side, go for a submersible heater
As there are some adjustable heaters, using which you can adjust the water temperature.
Better look for such heaters.
Do consider your room temperature while buying a heater.
Buy a product made up of high-quality material
Find a suitable location to place your heater
Other Important Things For Fish Tank
Apart from the heater, filters, gravel, air pump, decorations, and fish food are important
And yes do not forget to add fish too…
How many filters are there? Biological, chemical and mechanical, there are three types of filtration. Biological filtration is concerned with fish waste. Chemical filtration works to remove the ammonia etc. And mechanical filtration traps particles such as leaves etc.
How many fish can you have in your aquarium? Generally, it’s better to have 1-inch fish for at least 1 gallon of water. 2 or 3 gallons would be appropriate.
How long can fish stay alive without being fed? You might be away from home and cannot feed your fish. Don’t worry. Unlike humans, fish do survive even without being fed for a week or 2.
