How to choose the right heater for your aquarium?
There are 3 elements to consider to determine the right heater for your aquarium size:
- Room temperature
- Aquarium water volume
- Desired temperature.
Most aquarium experts recommend that you determine your heater’s power in terms of watts per gallon (WPG). Typically, you will need around 2.5 to 5 watts per gallon in your tank.
So, for example, a 10-gallon aquarium would need a 25- to 50-watt heater.
Still, this is only a rough estimate—you will also need to consider the room temperature to make an accurate calculation.
If your room temperature is low, you will need a larger heater to raise the water temperature in your tank—a cold room may require more than 5 watts for each gallon of water.
Follow our recommendations to choose the right heater for your aquarium.
KIND REMINDER: if you have a very large aquairum you are suggested to buy 2 heaters - put one at the left and another one at the right. This will allow your aquarium to have faster heating and more constant temperature.
Digital Electronic
This aquarium heater features a digital thermostat with built-in chips, ensuring precise temperature control. The advanced technology allows for accurate temperature regulation with high precision.
Indicator Lights
The fish tank heater is equipped with indicator lights for easy monitoring. A red light indicates that the heater is actively heating the water, while a blue light indicates that it is maintaining the desired temperature. Additionally, the digital display shows both the current water temperature and the target water temperature.
Easy to Set
Setting the desired temperature is a breeze with this heater. It has a single set button for easy operation. Pressing the button once increases the temperature by 1℉. When the temperature reaches 93℉, pressing the button again will reset it to 59℉. Press and hold the set button for 5 seconds to switch from ℉ to ℃.
Fully Considerations for Undesired Situations
Dry Run Protection
The fish heater has a safety feature that prevents it from running dry. If it's not fully submerged in water, an error code (E1) will appear. Simply submerge the heater completely in water to remove the error code and allow it to function properly.
Overheat Protection
The aquarium heater has an overheating protection feature. If the water temperature exceeds 95℉ or 35℃, the heater will automatically stop working and display HH. It will resume heating once the water temperature drops to below 93℉ or 34℃.
Memory Function
After a power cut, there's no need to worry about reprogramming the turtle tank heater. The thermostat stores the last temperature setting, so when the power is restored, the heater will automatically resume its previous setting.

I had an issue with the water freezing but didn't want it to get too hot. This allowed me to set a temperature and let it regulate. The only issue I have is the power cord is too short so I need an extention cord, but that's because my use is not for a fish tank

Very good purchase. Accurate with temperature, built-in thermostat console is very useful. I dont have to place the thermometer to see the temperature.

Works good but no decrease temperature button. You have to go past max temp before it resets. Use in a 40 breeder. Works ok like any other heater.

When the water level went below the heater, the Dry Run Protection did NOT activate which caused the encasing to start melting creating a giant fiasco in our house. The entire tank filled with smoke. Thankfully we caught it before a complete disaster. We won't be buying this brand anymore. (Bought 9/21/24, malfunctioned on 12/27/24)

Took a little bit of time to figure out the sensor. Still kinda figuring it out still. But it's doing it's job and keeping my 80 gallon tank warm. The price wasn't bad. And it seems like it'll last a while.
