Directions for Use
Preparation:

Dosage:
-
Use 1 gram of KoiGuard™ Prazi per 100 gallons of pond water.
Dissolving the Formula (The KoiGuard Pro-Tip):
- Do not just sprinkle the powder on top of your pond. 100% Prazi repels water. To break the water tension, place your required dose into a sealed jar or water bottle filled with pond water.
- Shake aggressively until it forms a milky slurry.
Application:
Pour the thoroughly mixed slurry directly into a high-flow area of your pond (like a waterfall or skimmer return) to ensure rapid, even distribution.
Treatment Duration & Protocol:
- Day 1: Apply your initial dose.
- Day 7: Perform a 25% water change and repeat the exact same dose. NOTE: KoiGuard Prazi is most effective on adult flukes, not eggs. This mandatory second treatment is to target any pests that were in a resistant egg stage during the first application.
- Day 14: Perform a final 25% water change and turn UV clarifiers back on.
