AQUARIUM HEATING 101 | Essentials


Due to the huge volumes of water tropical fish live in naturally, the large changes in temperature that can occur in a home aquarium, just do not happen. 

These changes can cause all sorts of health issues, and the sort of temperature movements that can occur, sometimes even overnight- can cause disease in even the toughest of species kept. This does not occur, even in tropical and sub tropical areas when a thermostatic aquarium heater is installed in the aquarium. 

It's essential to research the specific needs of the species of fish being kept in an aquarium and to provide appropriate heating if necessary. It's also important to monitor the water temperature regularly to ensure that it remains within a safe and suitable range for the fish. 

Bioscape, Hydor, Fluval, and Marina heaters are all popular options for aquarium heating. However, each brand offers different features and benefits that can impact their performance and suitability for different types of aquariums.
