What should the proper chlorine levels be?

Your Chlorinator is designed to run when your water pump is in operation. It will not produce chlorine if the water is not moving through the system.

You need to ensure that the water pump runs long enough to maintain the correct sanitizer levels as shown below. (A minimum of a eight-hour water pump run time is usually required.)

According to the National Swimming Pool Foundation, on a residential pool application the free available chlorine levels should not fall below 1 part per million. (Certified Pool – Spa Operator Handbook, 2006, 2-3)

Ideal chlorine levels range from 2 to 4 parts per million in pools, and from 3 to 5 ppm in spas.

Therefore, you will need to monitor your chlorine levels in your pool and adjust the water pump runtimes accordingly.

What do I do if I don’t want to run the pool pump that long?

If the pump is running shorter run times per day, you may need to do the following things to compensate for the higher chlorine needs.

  • Increase the purifier output percentage on the chlorinator
  • Increase the cell power (These higher levels can decrease the life of your cell)

Do I need to run the chlorinator longer when the water is hot?

Yes. In the summer months, chlorine will be used up quicker. As a result, you will need to increase the time the chlorinator operates or adjust your chlorine output or power levels to compensate.
