Instructions - Shock Treatment (for green or cloudy water)

1. Calculate the volume of water in the pool.
2. Thoroughly brush off any algae that may be clinging to the pool surfaces.
3. Adjust the pH to 7.0-7.2
4. Add 700g per 50m³ (11,000 gals). Broadcast the product evenly over a wide area in the deepest part of the pool. It should only be used when bathing has ceased. For outdoor use, avoid facing the wind when dosing. For heavy algae contamination, double this dose rate may be required.
5. Run the filter for 24 hours, then backwash it and vacuum the pool thoroughly. Any remaining haziness in the water should be removed using one our range of water clarifiers.
6. To help prevent a recurrence, ensure that free chlorine levels never fall below 1mg/l* (ppm) for unstabilised or 2mg/l* (ppm) for stabilised chlorine pools. Also dose the pool with Long Life Algicides.
