SANITIZE

Your pool stays clear and clean with hth® sanitizer products, designed to effectively guard against bacteria, algae, and other organisms. We offer two types of chlorine-based sanitizers - stabilized and unstabilized.

Sanitize Products
blue sparkle skimmer tabs
Blue Sparkle Skimmer Tabs

Overstabilization is caused by excessive cyanuric acid (CYA) levels in pool water, which render the chlorine ineffective.  HTH Blue Sparkle Skimmer Tabs are non-stabilized (contains no CYA), so there is no chance of overstabilization. HTH Blue Sparkle Skimmer Tabs will work in skimmers only.  Start off by adding 1 tablet per 10,000 gallons of pool water as often as needed to maintain a free available chlorine residual of 1 - 4ppm.  

  • Non-stabilized (contains no CYA), so there's no chance of overstabilization
  • For skimmer use only
  • Slow dissolving yet fast acting

Available in 5.5 lbs and 17.7 lbs
