Importance Of Aquarium Heater
Heat is essential for all tropical fish, as it helps to regulate their metabolism and maintain their immune system.
Without a heater, tropical fish are more susceptible to sickness and disease. In addition, heat helps to create a more natural environment for fish, as they would typically live in waters that are warmer than most aquariums.
As a result, installing a heater in your aquarium is one of the best ways to ensure the health and wellbeing of your fish.
How Aquarium Heaters Work
Aquarium heaters are devices used to raise the temperature of water in aquariums. Most aquarium heaters use an electric coil to generate heat, which is then transferred to the water.
The aquarium heater must be placed in the aquarium so that the water can circulate around it.
As the water circulates, it picks up heat from the coil and transfers it to the rest of the aquarium.
Aquarium heaters typically have a thermostat that can be used to set the desired temperature.
The thermostat will turn the heater on and off as needed to maintain the aquarium at the desired temperature.
Aquarium Heaters And Their Needed Wattage
Aquarium heaters come in a variety of sizes and wattages, so it's important to choose the right one for your aquarium. The size of your aquarium will determine the recommended wattage for your heater.
For example, a small aquarium (5-20 gallons) will require a heater with a wattage of 25-75 watts, (25-40 gallons) aquarium will require a heater with a wattage of 75-150 watts, while a larger aquarium (40-75 gallons) will require a heater with a wattage of 150-250 watts.
Some aquarium heaters also have multiple settings, so you can adjust the temperature to meet the needs of your fish.
When choosing an aquarium heater, it's important to consider the size of your aquarium and the specific needs of your fish.
With a little research, you can find the perfect aquarium heater for your tank.
How To Tell If An Aquarium Heater Is Broken
If your aquarium heater is broken, there are a few things you can look for to tell. First, check the aquarium temperature.
If it is significantly cooler than the temperature you set it at, then the heater may be broken. Another way to tell is by looking at the aquarium water.
If the water is cloudy or discolored, it could be a sign that the heater is not working properly. Finally, listen for any strange noises coming from the aquarium heater.
If you hear a loud bang or Pop noise, it means that the heating element has probably blown and will need to be replaced.
By being vigilant and checking for these signs, you can tell if your aquarium heater is broken and take steps to fix it.
