Pool Season Cal-Hypo Shockwave

This formula is highly concentrated with 68% available chlorine, making it a fast-acting solution designed to rapidly sanitize water and clear up cloudiness. Unlike slower-dissolving tablets, this granular form is intended for immediate, powerful treatment of bacteria and algae.

It is versatile enough for both. You can use it as part of your regular weekly maintenance regimen to keep water balanced, or apply it as a shock treatment to quickly address cloudy water and organic contaminants.

To prevent bleaching or damage to your pool liner, it is best to dissolve the granules in a bucket of water before pouring the solution into the pool. Always add the chemical to the water, never water to the chemical, and distribute it evenly around the perimeter.

Dosage depends on your specific pool volume and current water conditions, such as algae levels or cloudiness. Always check the label instructions on the pouch for the precise amount required per 10,000 gallons of water to ensure you are treating the pool safely and effectively.

You should wait until the chlorine levels have returned to a safe, recommended range, typically between 1 and 4 ppm. It is generally advised to wait at least 8 to 24 hours after application before re-entering the water to ensure the shock has fully circulated and dissipated.
