How does Aqua Prazi benefit my koi pond fish?

  • By gently removing deadly bacterial disease causing koi flukes.
  • Aqua Prazi will not harm your koi fish or set back your pond filter like many other koi fluke treatments.


Start with a 10% pond water change or more. Remove carbon from your pond filter, DO NOT shut off filter. Shut off U.V. light only, for 24 to 48 hours, do not shut off water pump to U.V. Shut off protein skinner.

One gram of Aqua Prazi treats 100 gallons, 10 grams treats 1,000 gallons. Add Aqua Prazi to one quart of pond water and shake vigorously for 3 to 5 minutes. Add this mixture to a 4 to 5 gallon bucket of pond water and mix well.

Two treatments work the best. The first treatment will kill all the live flukes. The second treatment, 3 days later will kill all the young as they hatch from their eggs.

No water changes for seven days from the first treatment.

Distribute the mixture around the edge of the koi pond or directly into the skimmer or filter outlet to achieve maximum distribution in the pond water. Do not use any other koi pond medications or treatments. FDA prohibits the use of this product on fish used for human consumption.

Note: One level tablespoon of Aqua Prazil for fish will treat approximately 500 gallons. Aqua Prazi is an excellent koi medication for treating flukes.

There are no precautions when using our Aqua Prazi praziquantel for treating koi pond fish flukes, it’s the safest, most effective koi pond prazi medication treatment on the market for treating koi pond fish flukes. Aqua Prazi does not stress your koi pond fish, burn their gills or set back your pond filter.

Our Aqua Prazi is manufactured in a FDA approved lab. Plus, Aqua Prazi praziquantel will also treat your koi pond fish for tape worms. In order for Aqua Prazi to its job, it’s very important that all carbon is removed from your pond filter and the light of your U.V. is shut off for the first 24 to 48 hours. No pond water changes for seven days. At the end of seven days no pond water change is needed. However, proper koi care takes at least a 10% water change once a week which helps keep your koi pond fresh and improves your koi fish health.


Q: How often should I use Aqua Prazi in my koi pond fish pond?

A: Aqua Prazi should be used on new koi pond fish in quarantine, unless you can check a scrape under a microscope and are sure your new koi pond fish do not have fluke parasites. Treat with Aqua Prazi if your koi pond fish show the symptoms listed under Parasites Koi fish Flukes on this web site.

Many koi pond keepers find it a good practice to treat their koi pond fish for fluke parasites as soon as their koi pond fish start to eat in the spring. Plus, once before they put their fish to sleep in the fall. This is a very good koi care practice.


Any koi pond fish medication treatment that is used when not needed or overdosed becomes useless when you have a real problem. The parasites or bacteria become resistant to the treatment. I think a good example of this is “salt”. Years ago you could use a safe, natural treatment like salt to treat many of the small koi fish pond parasites like costia, trichodina and others.

Now because of the overuse and increase in the amount of salt used by pond keepers and many foreign koi breeders, we now have strains of salt resistant costia and trichodina and others. Just because some pond keepers and koi breeders thought more was better we lost a very safe natural treatment.


Q: Will we lose one of the safest, most gentle fluke treatment we ever had?

A: I could see this OVERKILL of a very good koi pond fish treatment problem happening to Prazi. I’ll never forget the OLD DAYS of the harsh, gill damaging treatments for fluke parasites we used. The koi pond fish medication treatments were more damaging and stressful to the koi pond fish than the fluke parasites.

Talking with some pond keepers, I keep hearing the same old story about prazi that I heard about salt, OVERDOSEOVERDOSEMORE IS BETTER!! NOT TRUE!! Please don’t follow this misleading advice.

Double check your calculations!
If you treat your koi pond fish for flukes with Aqua Prazi and you’re sure by using a microscope that your koi pond fish still have fluke parasites, double check the calculations of the number of gallons in your pond water and the dosage of Prazi is correct, then treat one more time.

Are you really willing to lose a safe, gentle koi fish pond treatment for flukes like Prazi, only to be left with HARSH CHEMICALS?

Ask yourself another question, are the pond keepers that are overdosing prazi pond treatments for flukes, using PURE prazi or the “CUT” (fillers added) prazi that is now being sold on the market by some greedy vendors?
