How to Add Chlorine to a Saltwater Pool

Chlorine is the chemical used to sanitize pool water and remove bacteria and algae. Traditionally, pools use chlorine tablets and chlorine shock treatments to maintain proper chemical balance. Saltwater pools are an alternative to chlorine pools and rely on a chlorine generator to distribute and maintain chlorine levels in the water. However, there may be times, such as in the case of algae infestation, when you will still need to shock treat your pool by adding chlorine. Though this will not harm your saltwater pool or equipment, you should add chlorine with caution and monitor the chemical levels.

Chlorine keeps the pool water clean and free of algea.

Step 1

Remove floating debris from the surface of the pool with the pool net.

Step 2

Turn off the saltwater chlorine generator for the duration of the shock treatment.

Step 3

Fill the bucket half full with fresh water.

Step 4

Pour the dry shock product into the water, adding 1 lb. at a time. Often, shock treatment products come in 1-lb. packages to aid with measurement.

Step 5

Stir the mixture with a pool pole or stick.

Step 6

Pour the solution into random areas of the pool to spread the shock treatment through all areas of the pool.

Step 7

Repeat the process until you have treated the pool with the full dosage of the shock product. This will vary depending on your pool's water volume and the shock product manufacturer's instructions.

Step 8

Allow the shock treatment to sit overnight and test the water chemistry with water test strips the following morning. A pool should have a chlorine level between 1.5 and 3.5 parts per million.

Step 9

Turn on the saltwater chlorine generator once the shock treatment is complete.
