How to Use

Routine Pool Shocking

Add 1 lb of BioGuard Basic Shock per 12,000 gallons of pool water into the deepest area of the pool. Published directions state to apply while the filter and pump are not operating, then operate the pump and filter continuously for 4 to 8 hours after product addition.

For best results, shock pool water weekly and reapply after heavy pool use, high temperatures, or rainfall.

Brush pool surfaces while the filter and pump are operating. Add 1 lb per 12,000 gallons directly to the pool water in areas of heaviest algae growth, then operate the pump and filter for 24 hours.
