The purest salt formulated especially for swimmingpools and spas with chlorine generators, Aquasalt is produced using the Evaporated Food Grade Salt Process. Your pool or spa's chlorine generator converts Aquasalt into chlorine which in turn helps to remove contaminants from your water. With Aquasalt, not only will you enjoy soft, silky water that's clean, clear, and sanitized pure, you will also eliminate the irritation, harshness and strong odor that's typically associated with chlorine.
