What it does:

Smart Shock is the preferred shock product for the BioGuard Care System. Weekly use of Smart Shock keeps the water crystal blue and sparkling. It oxidizes organic contaminants that cause cloudy water, musty odors and eye irritation. It also kills bacteria and algae, and clarifies the water using a filter enhancer. Smart Shock buffers the pH to provide brilliantly clear water with no cloudy residue and without increasing the pH.

When/Why does ALEX recommend:

If selected as the oxidizer for boosting a low free chlorine residual or breaking up smaller amounts of combined chlorine. If higher levels of combined chlorine exist, Smart Shock will be overridden with a more appropriate product.

Application instructions:
Routine Maintenance: Add 1 lb. of Smart Shock per 12,000 gallons directly to the pool with the pump running. Run the filter 4 – 8 hours after applying. For best results, apply weekly as part of your maintenance routine.

For treatment of resistant algae: Establish 1 – 4 ppm free chlorine residual. Then with the pump running, broadcast 5 lbs. of Smart Shock per 12,000 gallons into the pool. Brush up any undissolved product. Wait 15 minutes, then add 40 oz. of Back Up per 25,000 gallons, following Back Up label instructions. Circulate continuously for 24 hours, then brush the pool thoroughly.

NOTE: Avoid physical contact with product. Do not store near petroleum products. Follow safety information on label instructions. Store in a cool, dry place. Keep out of the reach of children.

Test chlorine level prior to re-entry. Re-entry into treated swimming pools is prohibited above levels of 4 ppm chlorine due to risk of bodily injury.
