Fritz Expel-F is a safe, veterinary-strength, and highly effective anti-fungal medication designed to treat true fungal infections in both freshwater and marine aquariums. Fungal infections—often characterized by white, patchy, cotton-like growths on the body, mouth, or fins—typically occur as secondary infections following a physical injury or wound. Powered by fluconazole, Expel-F provides a fast-acting treatment that halts the spread of pathogens like Saprolegnia and Ichthyophonus hoferi, saving your fish from fatal infections without coloring or clouding your aquarium water.
Key benefits
Fast-Acting Anti-Fungal: Targets and eliminates true fungal infections, including cotton-mouth, body fungus, and tail rot.
Easy Packet Dosing: Pre-measured powder packets take the guesswork out of dosing, ensuring a precise and safe therapeutic level every time.
Safe for Most Invertebrates: Specially formulated to be safe for use in systems containing corals, snails, shrimp, clams, and other crustaceans.
Fresh and Saltwater Safe: Equally effective in freshwater community aquariums, fish-only saltwater tanks, and reef systems.
Bryopsis Control: As an added benefit, the active fluconazole in Expel-F is highly effective at eliminating nuisance Bryopsis algae.
