Unfortunately, it is not easy to say how many chlorine tablets you should add to the swimming pool or how often you need to add them. The chlorine tablet dosage does not depend solely on the volume of the swimming pool. A lot of other things also play a role, such as:

  • The number of hours of sunshine and the UV valueThe reason being that the chlorine value is degraded by the UV rays of the sun.
  • Leaves and insects in the swimming poolLeaves, insects and other dirt cause the active chlorine to become exhausted
  • The number of hours swum per dayThe more swimming there is, the quicker the chlorine degrades
  • If the swimming pool isnt used much, be sure to check the water quality once a week using a water tester. If the pool is used more than 2 days a week, the water quality needs to be checked 2 to 3 times a week.

    If the pH value is good, check whether the chlorine tablet has completely dissolved or not. Once the chlorine tablet has dissolved, it is best to add 1 chlorine tablet per skimmer.

    Before you can swim in the pool, wait for the amount of time recommended on the packageusually at least eight hours for chlorine-based shock treatments. You only have to wait as little as 15 minutes if you use non-chlorinated shock treatments.

    To be safe, it’s best to measure the amount of free chlorine in your pool to make sure it is 3 ppm or slightly less before swimming. It is dangerous to swim in a pool with high chlorine concentration. If necessary, you can use chlorine reduction reagents.
