What to use when pool water hold chlorine?

* Adjust the pH level of the pool water. Chlorine is most effective at a pH level of 7.2 to 7.8. If the pH level is too high or too low, the chlorine will not be as effective at killing bacteria.

* Shock the pool. Shocking the pool is a process of adding a large amount of chlorine to the pool water all at once. This can help to kill bacteria and other microorganisms that may be present in the water.

* Use a chlorine stabilizer. A chlorine stabilizer is a chemical that can help to slow down the breakdown of chlorine in the pool water. This can help to keep the chlorine levels in the pool water consistent.

* Cover the pool when not in use. This can help to prevent evaporation, which can lead to the loss of chlorine from the pool water.

* Avoid using sunscreens and other personal care products that contain oils or alcohol. These products can break down chlorine and make it less effective.

* Rinse off before swimming. This can help to remove any dirt, sweat, or other contaminants from your body that could react with chlorine and make it less effective.

If you are still having problems with chlorine levels in your pool water, you may need to contact a pool professional.
