PraziPro treats parasites like flukes, tapeworms, flatworms, and turbellarians. When PraziPro is added to an aquarium it will quickly kill external parasites in 24 to 72 hours.

What can kill flatworms?

To kill them — and that's important to do — spray them with strong orange oil mixtures. Or, even better, put them in a jar with a strong orange oil mixture. Remember, orange oil mixed stronger than 2 ounces per gallon of water will burn or even kill plants.

What does PraziPro treat?

This Prazipro can be used in freshwater, marine tanks and in ponds. The bottle states it treats Flukes, Tapeworms, Flatworms and turbellarians. This makes Prazipro a great dewormer.
