Frequently Asked Questions about Liquid Pool Shock
With so many sanitizer options available on the market today, it can be hard to choose which one is best for you. Here are some of the answers to common questions about liquid pool shock.
How much liquid chlorine is needed to shock a swimming pool?
The amount of liquid chlorine needed to shock a pool depends on the pool's size and current chlorine levels. For one-time shock treatments to remove algae and other organic contaminants, a dosage of around 1.5 to 2 gallons per 10,000 gallons of water should do the trick.
For weekly shock treatments using liquid chlorine, you should be adding around 1 gallon of liquid shock per 10,000 gallons, per week. During hoter weather or higher bather load, you may need to shock more frequently.
How do I shock a pool with liquid chlorine?
To shock a pool with liquid chlorine, first ensure the pump is running. Pour the recommended amount of liquid chlorine evenly around the pool's perimeter, especially around deep areas.
Let the pump circulate the water for at least 8 hours, and avoid swimming until chlorine levels return to a safe range, ideally between 1-3 ppm.
Remember: Keeping your pH level balanced is crucial to ensure that the liquid chlorine is able to do its job! As pH level rises, all forms of chlorine become less and less effective.
How much liquid shock should I add to a 15,000-gallon pool?
For a 15,000-gallon pool, you’ll generally need 1.5 to 2 gallons of liquid chlorine. This may vary depending on chlorine levels, algae presence, and other factors. A pool shock calculator can help determine the exact amount based on your pool's specific needs.
