You cannot be a passionate aquarist without tank heater in your aquarium.

They are the best tool to maintain and regulate water temperature of your tank. Fishes are cold-blooded animals; this means they lack the ability to regulate their body temperature according to their environment like we humans do. That’s the reason tank heaters are the must-have.
Meet me. A tank heater.

Usually, we are of three types only.

Submersible tank heater
Among all, this type is the most common one. It’s small and compact in size. You can easily identify this. It will look like a rod. You can place this type either vertically or horizontally. Most importantly, it is completely submerged type.
Substrate tank heater:
Such type is ideal when you have small space in the tank because this tank heater type can be easily placed beneath the substrate. They are also called under gravel heaters. They are quite expensive that’s why they are not as much common as submersible tank heaters.
In-filter water heater:
These type of heaters are placed inside the canister filter. They are perfect for that aquarist who loves to keep aggressive fishes as these fishes fight with instruments as well.
This was a brief and short introduction about me and my types.
If you are looking for an appropriate and high-end tank heater then there is a glad tiding for you.
You have landed onto the right page.
