The Size Of The Heater

The aquarium heaters come in a variety of sizes for you to choose from. A larger aquarium has a huge amount of water and hence requires a largely sized heater. The smaller aquariums require smaller water heaters.

However, there are aquarium heaters that are versatile. They can be used by a huge size range of aquarium heaters.
