Pool shock chemicals provide a quick fix for improving chlorine levels in your pool but can also make your pool unsuitable for swimming. Generally speaking, after adding pool chlorine shock to your swimming pool, it is best not to swim for several hours.

      Chorine is added to our pools to kill bacteria and other organic contaminants. Because chlorine becomes ineffective once it binds to bacteria, it is important that chlorine levels are always monitored. When these levels get very low, we turn to the pool shock. Shocking involves adding lots of chlorine to a pool quickly to kill or prevent the build up of contaminants. When adding a pool shock chemical to your pool there are some important tips to remember. Add the pool shock at the end of the day, when everybody is finished swimming, and let the swimming pool shock go to work overnight with the filter running. Always test the level of chlorine in your pool after you add the pool shock and before you go swimming again to make sure the levels are safe.Swimming pool chemicals are obviously an important aspect of maintaining water clarity. Swimming in crystal clear blue water is ideal and as such we utilize chemicals to enhance the quality of our water. Chorine is added to our pools to kill bacteria and other organic contaminants but during this process, chlorine levels lower.
