When Should You Shock Your Pool?
Shocking helps by balancing pool water after contamination, like after a pool party or after heavy rain. It also prevents algae growth and is a more effective treatment than algaecide if you already have a significant algae bloom.
Pool shock also helps remove chloramines, or combined chlorine, and helps revitalize your existing chlorine. That means your regular chlorine can continue to do its job of sanitizer your water.
What Type of Shock Should You Use?
If you' re dealing with a significant water problem, we recommend using a chlorine-based shock, like calcium hypochlorite (cal-hypo) or dichlor shock. The powerful concentration of chlorine will help kill contaminants and algae. But because they will significantly increase the amount of chlorine in your water, your pool won' t be safe to swim in until your chlorine levels drop back down.
