To determine the amount of dry shock (calcium hypochlorite) to add to a 650-gallon pool, a general guideline is to use 1 pound of shock for every 10,000 gallons of water for a standard chlorination. Therefore, for a 650-gallon pool, you would typically use about 0.065 pounds (or approximately 1 ounce) to achieve a standard chlorine level. However, if you're aiming to raise the chlorine level significantly or are treating for algae, you may need to adjust this amount accordingly. Always follow the manufacturer's instructions and test the water afterward to ensure proper chlorine levels.
