Why is it necessary to have a cooling system?
Cooling system for freshwater aquarium
Water cooling is essential in the aquarium hobby , especially in the summer when the water temperature rises rapidly.
Excessive temperature swings can affect sensitive bacteria , as well as your aquatic plants and fish . It is therefore vital to regularly check the temperature of your tank so that it remains constant .
It is therefore necessary to have a fan in order to cool the water in your aquarium by allowing the circulation of air above your tank.
In freshwater aquariums , care must be taken to take into account the requirements of each species . Indeed, while a Discus needs water at 27-29° , a Neon requires water at 24-26° . Similarly with aquatic plants , a dwarf Anubias needs water between 23° and 28° while an Elodea thrives in cold water below 24° .
