Fritz Expel-P is a safe, fast-acting anthelmintic (deworming) medication and immunostimulant designed to treat internal parasites in both freshwater and saltwater aquariums. Powered by Levamisole HCl, Expel-P is highly effective against parasitic worms such as nematodes, roundworms, nodular worms, and hookworms (including stubborn Camallanus red worms). In addition to treating fish internally, this versatile treatment boosts your fish’s immune competence to aid recovery and can even be utilized as an effective coral dip to rid marine corals of flatworms and pest nudibranchs.
Key benefits
Powerful Deworming Action: Targets and eliminates difficult internal parasites, including nematodes, roundworms, and hookworms.
Boosts Immune System: Acts as an immunostimulant to help recovering fish rebuild their natural defenses and resist secondary infections.
Versatile Coral Dip: Can be used outside the tank as a targeted dip to safely clear corals of destructive flatworms and pest nudibranchs.
Safe for Biological Filters: Will not disrupt nitrifying bacteria, preserving your aquarium’s beneficial bio-filter during treatment.
Invertebrate and Plant Safe: Formulated to be safe for live plants and aquarium invertebrates like shrimp, crabs, and most snails.
