Fritz A+ Aquarium Salt is an all-natural salt that provides essential electrolytes that freshwater fish need to be able to take in oxygen and expel CO2 and Ammonia. Without these electrolytes, your fish might be at risk of serious health problems.
A+ Aquarium Salt should be added only when reducing stress in your fish when they enter a new aquarium set up. It can also be used during water changes, as well as to aid your fish to recover from diseases. Perfect for internal problems including constipation, fluid retention and mild swim-bladder disorders.
