Test the salt level in the pool - Salt range: 0~9990ppm/10~100ppm; Check the salt concentration of saltwater pools and spas that use a salt chlorine generator; It helps the salt chlorinator to work more efficiently with the proper salinity value. Test the pH level of the pool - pH: 0.00~14.00; Recommend a pH level between 7.2 and 7.8 for different types of pools (fiberglass, vinyl pools, and tiled pools). When pH is back in range, for optimal performance and cleaner water. Test Strips VS Digital Meter With test strip testing, you will need to guess which pool value is based on the color of a strip; The digital tester, however, will give an exact reading, so no guesswork is necessary. In addition, using enough test strips will increase your costs in the long run. Multifunction Salinity Tester: The Te ...
