API FURAN-2, containing active ingredients nitrofurazone + furazolidone + methylene blue, is a broad-spectrum anti-bacterial drug that can be used as a treatment to control a wide variety of freshwater and marine fish/seahorse diseases - especially helpful for skin infections (fin & tail rot, open red sores, gill disease, blisters, ulcers) that have not become advanced (systemic).
If the infection has become systemic, FURAN-2 can be combined wtih KanaPlex (active ingredient is Kanamycin) for a very effective broad antibiotic treatment. This combination is especially helpful for marine fish/seahorses to fight the gram-negative bacterial disease, Vibrio, that is often the cause of infections.
