How to Use Saltwater in a Pebble Tech Pool

Add 50 pounds of iodine-free table salt for every 2,000 gallons of water. For example, a 12-by-24-foot inground pool holds approximately 13,000 gallons of water, which requires about 325 pounds of salt to chlorinate the saltwater pool sufficiently, according to Pool Solutions.

Brush the salt around using your long-handled pool brush. Brushing the salt around in the water helps it dissolve and get to the filter quickly, where it can do its job in the saltwater chlorinator. The saltwater chlorinator works together with a generator to take the table salt and turn it into chlorine through electrolysis.

Test the level of salt in the water using salt test strips. You can find these at any pool supply center. The level of salt should read 4,000 parts per million. Adjust salt as needed to reach this level.

Add a pool stain preventive during your beginning-of-the-year maintenance. Pebble Tech recommends adding this preventive to saltwater chlorinators to counteract any dissolved solids that can develop on the pool floor and walls due to the salt content.

Check the low salt indicator on the saltwater generator or test the water periodically with salt test strips. Add salt as needed to keep the level of salt at 4,000 parts per million. Typically, you won't need to add salt more than once a year, due to runoff, rainfall and filter backwashing.
