Prazi Pond Plus (Praziquantel - pronounced "pratz-eh-KWON-tel") is the hands-down best treatment for flukes available to pond keepers. It is the most gentle, yet effective treatment and also rids fish of any internal parasites or worms. It is safe, requires one dose, no water changes, and has no reef or filter effects associated with its use! Prazi will work with any amount of salt in the pond and is not water temperature dependent. Treatment with Prazi is recommended every spring as a preventative.

"PRAZI" is a filter and reef-filter* safe, effective treatment for fresh and saltwater flukes (trematodes) both monogenic and diagenetic. One application remains in the water long enough to kill all phases, when dosed correctly. No water changes are needed!
