The PROCLEAR® Spa Sanitizer delivers a more efficiently sanitized, easily maintained, and odor-free hot tub. PROCLEAR® significantly improves the look and feel of your water by providing a more consistent PH balance. Using trace elements of silver, PROCLEAR® kills bacteria more effectively than chlorine alone. Your spa water is not only brilliantly clear and soft, but gives you an alternative to chlorine-intensive treatments. Do not mix with Bromine, bromides or Biaguanides. Available in the U.S. and Europe, not available in Canada. 2890-185
