Tetra Parasite Guard uses quick dissolving, premeasured fizzy tablets to obliterate the external and internal parasites that plague your freshwater aquarium fish.
Parasite Guard uses fizzy tablets to get to work on your aquarium immediately. Use to treat external and internal parasites in tropical fish, including flukes, internal worms, lice, anchor worms, and flagellates associated with hole-in-the-head disease.
Directions: Add one tablet for every 10 gallons of aquarium water. For tank volumes of 40 gallons or larger, and for soft/acidic water, pre-dissolve tablets before adding to the tank. Remove carbon from the filter when Fungus Guard is in use.
Second Dose: Treatment may be repeated up to 2 times with 48 hours and a 25% water change between treatments. When treating anchor worms and fish lice, treatment may be repeated up to 3 times, with a week and 25% water change between treatments.
Caution: Do not use Parasite Guard in environments with crustaceans such as shrimp and crabs.
