PARAZORYNE HERBAL IMMUNE STIMULANT Parazoryne is a unique herbal immune enhancing stimulant which reduces skin flukes (Gyrodactylus), gill flukes (Dactylogyrus), ich (Ichthyophthirius multifillis), Oodinium, Costia (Ichtyobodo necator), Chilodonella and Trichodina. Just like Sabbactisun Parazoryne supports the immune system of the fish, causing parasites to be driven off. Parazoryne does not kill parasites directly. Since they cannot return to the fish during the treatment, the majority of the parasites will starve. Parazoryne is no disinfectant, it restores the natural balance. After a treatment there will be some parasites present, as will be on any healthy fish. Parazoryne does not kill the nitrifying bacteria and do not reduce the water quality, which saves time and money. During treatment with Parazoryne the fish can be normally fed and filtration will remain in normal operation. Those factors will add to the wellbeing and recovery of the fishes. Safe for all fresh and brackish water fish species, invertebrates and aquatic plants. Non toxic. Do not cause resistancy. No harmful residues: Parazoryne is completely biodegradable
