Ready to test
At this stage, both traditional and saltwater pools are ready for water testing and balancing. To do this, take an elbow-deep water sample from an area in the pool away from the return lines. Test for and adjust total alkalinity (TA), calcium hardness, CYA, and pH as required to properly balance the water.

Saltwater pools will require one additional step, which involves testing the water for salt levels. Maintaining an appropriate salt level is critical for the ECG to function properly; therefore, it is important to make sure salt levels are adjusted to fall within the recommended range provided by the ECG manufacturer (typically between 3,000 and 4,000 parts per million [ppm]). This test is usually performed using test strips or an electronic meter. If using a meter, make sure the water temperature is at least 15 C (59 F) or higher.
Once the water is balanced and salt levels are in the proper range, run the ECG on its highest level of chlorine output for at least 24 hours to establish between one and four parts per million of free chlorine. Then, decrease the output or pump runtime according to the manufacturer’s instructions to maintain the proper chlorine level throughout the season.
TIPS FOR MAINTAINING WATER BALANCE |

![]() Once saltwater pools are ready for the season, maintaining balanced water is one of the keys to a great swimming experience, all season long. Balanced water simply means pool water chemicals and minerals are within their target ranges for optimum performance, as follows:

Making the switch to salt
For customers who have been contemplating a conversion to a saltwater sanitization system, spring is the best time to make the switch. Pool water is typically diluted at startup, with fewer traditional chemicals, so it is easier to create a balanced saltwater pool. If a pool needs to be partially drained for a repair, or if a liner needs to be replaced, it can be cost effective to convert at the same time. The general idea is for customers to get a full season of saltwater swimming by converting in the spring.
