This is why turtle tank heaters are a crucial addition to your aquarium set up.

How to Heat a Turtle Tank

Generally, turtle owners who keep adults turtles do not actually have to heat their turtle tank but if you have a baby turtle you will need one.

This is because as you can image baby turtles are growing and you will want their metabolism to be active, to be able to digest their food quickly so they can consistently grow.

The adult turtles will no longer grow and they will not be using as much energy to go into the process of growing, so it’s not necessary to heat your adult turtle tank.

Adult turtles are very resilient and can withstand a wide range of temperatures.

Higher temperatures also help turtles fight off disease and illness more effectively.

As for the temperature in the turtle tank depending on the turtle you own, you can follow the list below:

Conclusion

A precaution you can take is to have a heater guard so you won’t run into the situation of your turtle breaking the tank heater, just be sure it will fit the heat that you will buy.

Make sure you also have a thermometer so that you can test the temperature of the water to make sure it’s staying pretty consistent.
