Information On Pool Shock

As something required weekly for proper pool maintenance and upkeep, you’ll go through a lot of shock during the summer months. Whether you prefer chlorine or chlorine-free shock, we have you covered at Choose between shock, super shock or mega shock to maintain your pool or fight algae, and order the amount you need by weight.

When Should I Shock My Pool?

During the swimming season, it is recommended to shock your pool approximately every 7-10 days. Additionally, you should shock your pool after a rainstorm, pool party, or when there is a high bathing load. This will help break down any combined chloramines and improve the effectiveness of your sanitizer. Shocking your pool also helps restore chlorine levels by eliminating bacterial buildup.

How Much Shock Should I Use?

The amount of shock required depends on the size of your pool, the reason for shocking, and the type of shock you are using. Always refer to the recommended amounts mentioned on the packaging or on our website. As a general guideline, you can use the following estimates:

  • To increase chlorine levels, it is recommended to use ½ pound (or half a bag) of shock for every 10,000 gallons of water.
  • If your water appears cloudy, use 1 pound (or one bag) of Shock for every 10,000 gallons.
For treating algae, it is suggested to use 2 to 6 pounds (or 2 to 6 bags) of shock per 10,000 gallons, depending on the severity of the algae. The greener and darker the water, the more shock you should add. Note; if you opt for a stronger shock, you may require a lesser quantity.

What Type Of Shock Should You Use?

For regular maintenance, you can use either chlorine-free shock or chlorine-based shock. If you notice algae growth, it is recommended to use chlorine shock or super shock. In the case of an existing algae bloom, consider using super shock. For severe algae blooms, a higher dosage of super shock or mega shock should be considered.
