Aquarium salt is a useful preventive and therapeutic agent with two main applications:

• Removal of biological turbidity: It combats excessive growth of bacteria and protozoa, ensuring crystal clear water.
• Replenishment of inorganic compounds: It supplements trace elements required for the proper functioning of the aquarium's fauna and flora.

It is especially useful in stressful situations for fish, such as during transportation or acclimatization periods. It is recommended to be used preventively with every water change in the aquarium.
