Eliminate parasitic infections in both fresh and saltwater ecosystems with PraziCleanse – a safe, powerful, and effective treatment for skin and gill flukes, tapeworms, flatworms, and turbellarians. This remedy will not cause discoloration or cloudiness, nor harm plants or uninfected fish. For optimal results, administer one packet per 20 gallons and, after a 25% water change, repeat the treatment five days later. Remove any chemical filtration, including carbon, and turn off the UV sterilizer, if present, during the process; however, the water flow and aeration should continue to be maintained. Fritz Aquatics A.C.C.R. may also be used to counteract possible ammonia poisoning of the fish. Please note: this product contains metronidazole, known to California to cause cancer. 10 Pack; 190 mg praziquantel per packet.
