Treat fungus and bacterial infections quickly and safely with API's Pimafix Infection Remedy for freshwater and saltwater fish. Bacterial diseases are caused mostly by dirty aquarium conditions and adding infected fish. Fish that are injured and have open wounds are especially susceptible, even in seemingly clean tanks. Fungal infections, like cottony growth, and bacterial infections, like fin and tail rot, can damage tissue and other organs. Pimafix is an all-natural, broad-spectrum treatment made from the antifungal properties of the West Indian Bay tree. It is formulated to not only treat disease, but develop resistance. It's safe for reef aquariums and live plants and should not adversely affect the biological filter, alter pH or discolor water.
