The world’s first, ready-to-use liquid concentrate praziquantel treatment, this extremely safe and highly-effective formula helps fish hobbyists control unwanted parasites in their pond, freshwater or marine aquarium. Considered the quality leader in aquatic nutrition and health for decades, Hikari devotes a significant amount of time, money and resources into studying the needs of fish in both their natural environments and in aquatic laboratory settings in order to help them thrive in captivity.

Key Benefits
  • The world’s first, ready-to-use liquid concentrate praziquantel treatment is scientifically proven to be highly effective.
  • Treats potentially harmful parasitic conditions caused by flukes, tapeworms, flatworms and turbellarians.
  • Can also be used as a preventative to keep tanks safe and parasite-free anytime potential parasitic introduction is considered probable.
  • Not toxic to commonly kept aquarium animals and plants; will not negatively impact biological filtration.
  • Recommended for use in all aquatic environments including ponds, freshwater and marine aquariums.

Keep out of the reach of children. For aquarium or pond use only. Not for human or veterinary medical use. Do not use on food fishes.

A Proprietary Blend of Water-Soluable Ingredients, Oxybispropanol (As An Inert Solubilizing Agent), <5% Praziquantel By Weight.


For treatment of praziquantel-susceptible disease conditions in pond, freshwater and marine aquariums and ornamental pond fishes. AS A BATH: Start treatment with as large a water change as practical or start with new water. Any water used should first be conditioned with ULTIMATE or a combination of Liquid Buffered ClorAm-X and Stress-X to remove ammonia, chlorine and chloramines. Do not stop filtration, but remove activated carbon and stop foam-fractionation (protein skimming) and UV sterilization. SHAKE VIGOROUSLY before use. Measure Aquarium Solutions Liquid PraziPro at the rate of 1 teaspoon per 20 gallons of water to be treated. (1 fl. oz. per 120 gallons) Measure Pond Solutions Liquid PraziPro at the rate of 1 teaspoon per 32 gallons of water to be treated. (1 fl. oz. per 200 gallons) This produces a concentration of 2.5 mg/L. Distribute the proper amount around the edge of the aquarium or pond or directly in to the filter box to achieve the best overall distribution. A single treatment lasting 5-7 days is normally sufficient. Repeat as necessary, but no more than once every 3 to 5 days. May be used as a preventative, at the standard dosage, when disease is likely. Do not use with other drugs or disease treatments. May cause temporary foaming.

    Worked as advertised in treating my tank for tapeworms. Follow the directions, and be prepared to be severely grossed out!

    I've read the reviews and they're pretty positive. I also like that it's a small bottle in case it doesn't work!

    Testing product to see if it does the job. Heard good things about it so got the 1 ounce to try if it's the right product for me.
