Before use:
Balance pH to 7.2–7.8 and Total Alkalinity to 80–120 ppm.
Check metals: Test for copper levels first. If copper level is over 0.2 ppm, take measures to get the level under 0.2 ppm before using. Do not use with other copper-based products.
Calculate dosage: Use 1 pod per 10,000 gallons of pool water.
Clean the filter: Backwash or clean your filter and clear all debris out of the skimmer and pump baskets.
- Place the pod: Drop the correct number of pods directly into the skimmer basket.
- Run the pump: Keep the pool pump and filter running continuously for at least 24 hours to help the dry formula disperse.
- Disposal: Remove empty pod and discard on your next visit.
Ongoing Care
- For killing active algae: Raise free chlorine to 3–5 ppm. Clean or backwash the filter after 24 hours to remove dead debris.
- For prevention: Do not clean or backwash the filter for at least 2 weeks after use and use a new pod every 6 months.
