Waterlife Parazin is used to treat fish lice (Argulus), anchor worms (Lernea), gill flies (Ergasilus), and other insect/crustacean parasites/predators found in aquatic tanks. These organisms may be so small that they are invisible to the naked eye, and these parasitic predators can be very harmful and may even lead to the death of fish.

Usually, just a single dose is all you need to solve the problem. Parazin is safe with fish, plants, and filtration systems.

Precautions: Before use, read the instructions carefully. Turn off UV sterilizers and remove carbon and/or ammonia removers. They can be replaced after 10 days.

Dosage: 20 tablets / sufficient to treat up to 450 liters.
