Owning a swimming pool is a lot of fun for the entire family, but it requires maintenance in order to keep it clean and healthy for everyone to swim in. A shock helps keep all of your pool chemicals balanced and your swimming pool water crystal-clear.

Time Frame

Pool shock should be added every week to ensure a clean and green-free pool, but this can also be determined by the weather and amount of time you spend using the swimming pool. The higher the temperature and pool use, the more often you should shock, due to bacteria, algae and ammonia forming.

Always shock your pool at dusk or nighttime, in order to allow the shock to reach breakpoint oxidation. Shocking your pool in the middle of a hot, summer day would cause the sun to burn off 1ppm of shock every hour, causing it only to reach breakpoint for an hour instead of for eight to 10 hours.

Testing Pool Water

Testing the pool chemicals is important and should be done each time before adding shocking materials.

Test your pool water to see if it needs to be shocked by smelling the area around pool. If the water has a strong scent of chlorine, it requires shocking chemicals.

Purchase a pool test kit that has the ability to read total as well as free chlorine. Whenever these two chlorine reading numbers are not the same, the pool needs to be shocked. Amount and type of shock also should be determined by the type of pool system you are using. Shockers are available as non-chlorinated for non-chlorinated pools and chlorinated for chlorinated pools.

Adding Shock to Pool

If you are an average homeowner with a pool, you will most likely shock your pool once each week after running a test kit. Mix shock chemicals and water according to package directions. Always add shock to water, not water to shock, when shocking your pool. The shocker you have purchased will likely be a quick-dissolving chemical, but you can use the pool skimmer to stir it to speed up the oxidization process.
