Aqua Prazi — Pure Praziquantel

The go-to treatment for the most common koi parasites: gill flukes (Dactylogyrus), skin flukes (Gyrodactylus) and tapeworms. Aqua Prazi is pharmaceutical-grade praziquantel that clears the infestation without harming the beneficial bacteria in your biofilter — so you treat the fish without crashing the pond.

Dosage — 1 gram treats 100 gallons
Pond volume Aqua Prazi per dose
100 gallons 1 g
500 gallons 5 g (≈1 tbsp)
1,000 gallons 10 g
2,000 gallons 20 g
5,000 gallons 50 g
10,000 gallons 100 g
How to apply
  1. Weigh the dose for your pond volume (a gram scale helps).
  2. Add to ~1 quart of pond water and shake hard for 3–5 minutes.
  3. Mix that into a 4–5 gallon bucket of pond water.
  4. Pour around the pond edge, or into the skimmer / filter return for even spread.
Two-dose protocol: Treat once to kill live flukes, then again 3 days later to kill young that hatch from eggs. Both doses are needed for a complete clear.
Before you dose: test your water first — many "parasite" symptoms are really water-quality stress. Remove carbon and turn off UV during treatment, keep good aeration, and never mix Aqua Prazi with other medications. Sizes: 25 g, 50 g and 100 g.
Dosing per Aqua Meds label; ~10 g / 1,000 US gal ≈ 2.6 mg/L, consistent with the ~2 mg/L praziquantel bath standard for monogenean flukes (Noga, Fish Disease: Diagnosis & Treatment). Guidance only — not veterinary advice.
