BioGuard SaltScapes Pool Care - Test Strips Pack BioGuard SaltScapes Saltwater Pool Care System - Test Strip Pack Saltwater pools need to have water balance levels tested on a regular basis just like traditional chlorine pools. The amount of salt in your pool and the amount of chlorine being produced are independent of each other. Adding more salt to your water (above what is recommended in your owners manual) does not improve the efficiency or increase the generation of chlorine. SaltScapes Test Strips ensure correct salt and balancer levels to ensure the best swimmer comfort, equipment protection, and sanitizer efficiency.
