Fish tank heater control made easy: expert tips and advice | Aquaforest 

Maintaining the proper aquarium temperature is crucial for the health and well-being of its inhabitants. One of the key tools in achieving this balance is a fish tank heater. However, controlling the heater and ensuring the optimal temperature for your aquatic pets can sometimes be a challenge. Fortunately, with expert tips and advice, this task can become much easier. In this article, we will explore the importance of fish tank temperature, the role of a heater, and provide valuable insights on how to effectively control and maintain the perfect water temperature of your tank. Whether you are a beginner or an experienced fish keeper, these aquarium expert tips will help you create a comfortable and thriving environment for your underwater friends and keep your aquarium healthy.

Why water temperature in the fish tank is so crucial?

Unfortunately, fish will perish if the water in their aquarium becomes too warm or too cold compared to what they are accustomed to in their natural habitats.
Furthermore, the optimal water temperature for a freshwater aquarium will differ from the preferred temperature for saltwater marine life. To achieve the best outcomes, it is essential to conduct research on the specific fish species before bringing them home. This parameter has a huge impact on stress, and shock your fish, which can lead to increased susceptibility to disease.
Make sure to ascertain the water requirements of the fish, such as whether they need freshwater or saltwater. It is also crucial to determine the temperature range suitable for each kind of fish to ensure that the tank’s water is within the recommended temperature range for each individual fish. In the case of too cold or too high temperatures, it may be necessary to purchase or construct an aquarium heater or cooling unit.

Every type of fish has a specific temperature range in which they can flourish. In many instances, your fish don't require an exact temperature for their aquarium. In reality, freshwater fish can endure temperature fluctuations. Even in a reef environment, the temperature changes from 20-32°C throughout the day.
The main objective in your home aquarium is to maintain a water temperature that falls within the desired temperature for your fish, invertebrates, plants, or corals. You must therefore firstly know what properly the temperature range is for the inhabitants of your aquarium.

What if your tank temperature is too high?

Your fish extract oxygen from the water for respiration. Normally, your aquarium provides an abundant supply of oxygen.
When the water is warm, your fish become more active and require more oxygen. However, warm water actually holds less oxygen compared to cooler water. In severe cases, there may not be enough oxygen available and your fish might suffocate.
In addition, the beneficial bacteria in your aquarium rely on oxygen to break down ammonia. When there is insufficient oxygen, ammonia levels increase in the aquarium, displacing oxygen and resulting in damage to the gills of your fish. 

What's the solutions in that case?

  1. The easiest solution to cool water is reducing sources of aquarium light, dimming lamps and covering windows. You can start from it. If the requirements of aquarium don't let for it, we also have other solutions.
  2. Properly chosen filtration also has a crucial influence on the constant temperature of aquarium water.  It will maintain the well-being of the water quality and guarantee the thriving of the fish inhabitants without any potential dangers.
  3. Use Evaporative Cooling -  This process of cooling through evaporation happens when water turns into a gas and takes in energy from its surroundings. By promoting evaporation in a fish aquarium, it will absorb some of the heat in the water and reduce the temperature by a small amount. The first suggestion is to take off the cover of the aquarium so that water can evaporate more easily and heat can escape.
  4. Chiller - This is an external device to which you connect the pump pumping water from the aquarium. It allows the fastest reduction of the aquarium water temperature. This device allows you to reduce the water by 7 degrees Celsius in as little as 5 hours.

What if your tank temperature is too low?

Low temperatures can also harm your fish. When exposed to colder temperatures, these fish can experience reduced energy levels and become lethargic, ultimately leading to a high mortality rate.

Equip the fish tank with a good quality heater

An effective submersible aquarium heater will be equipped with an integrated thermostat that can automatically activate the heater when there is a variation in temperature. Certain heaters have only one temperature setting, whereas more sophisticated models utilize a timer or sensor to maintain a consistent temperature within the aquarium. To ensure tank temperature control, many individuals place their heater in the center of the aquarium, and there are specific heater types that are optimal for tanks of different sizes.

What temperature should a fish tank be?

You must constantly remember that the “ideal” temperature range depends on species of fish, corals, plants which you want to keep in the tank. It's good to notice that, you shouldn't keep fish of his max temperature range. For example: If your fish prefers temperature like 22°C– 26°C, then you shouldn't keep it at 22°C or 26 °C. It can be stressful for any creature.
Be conscious of the impact rising temperatures can cause on your fish and reef aquariums! Coral reef habitats are typically observed at a temperature of 29°C. The general recommendation is to maintain a reef aquarium at 25°C.
On a general note, standard aquarium fish species, found in both homes and businesses, ordinarily thrive in tank water temperatures between 24 – 26.5°C. This is applicable to a large proportion of tropical fish varieties, and such temperature range can also serve as a reliable starting point for most of the types of freshwater fish usually kept in fish tanks. Remember, keep your fish happy! 

How to maintain aquarium temperature?

One of the basic elements in saltwater, and freshwater aquarium setup is a thermometer, it will much help to check the temperature and maintain properly temperature of water. If you want to make it easier, you could buy an aquarium heater controller. How does it work? If your temperature drops too low, the heater will start heating your aquarium water, in reverse, if your aquarium water is too high, the heater will stop working, and the controller will be on a fan. You can buy it in local fish store or online. It's really comfortable!
