Who Should Buy This?
Pool owners with 10,000–30,000 gallon pools benefit most from weekly shock treatment. Cal hypo shock is ideal if you're battling chlorine-resistant algae, managing high swimmer load, or dealing with weather-induced water changes. This is the industry standard for affordable, reliable pool sanitation throughout the season.
Buying Tip
Always shock your pool in the evening or night to maximize effectiveness—sunlight breaks down chlorine before it can sanitize. Test water chemistry before applying, and maintain a chlorine level of 1–3 ppm after shocking. Store packets in a cool, dry place away from direct sunlight and organic materials.
