HTH 17.7 lbs. Pool Chlorinating Sanitizer Blue Sparkle Skimmer Tabs

Your pool stays clean and clear with HTH sanitizer products, designed to effectively guard against bacteria, algae and other organisms. We offer 2 types of chlorine-based sanitizers: stabilized and unsterilized. HTH Benefit: 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 cyanuric acid) (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 Gal. of pool water as often as needed to maintain a free available chlorine residual of 1 ppm to 4 ppm.
