HTH 5.5 lbs. Blue Sparkle Skimmer Pool Chlorine Tabs

Keep your indoor or outdoor pool clean and clear with HTH Blue Sparkle Skimmer Tabs. Just place a tab in your pool skimmer to destroy bacteria and organic contaminants without adding additional cyanuric acid (CYA) to the water that can lead to overstabilizing your pool. HTH Blue Sparkle Skimmer Tabs feature an innovated patented technology that provides long-lasting, slow-dissolving chlorination without adding extra cyanuric acid (CYA). TO USE: Use only in skimmer and skimmer basket. Skimmer basket should be free of all other water treatment products before adding the recommended number of Blue Sparkle Skimmer Tab(s). Place skimmer tab in the empty skimmer basket. Use 1 tab of the product per 10,000 Gal. of pool water. After 1 day of use, test free available chlorine (FAC) residual with HTH Multi-purpose 6-Way Test Strips, sold separately. Do not enter pool until the free available chlorine residual is 1 to 4 ppm (parts per million).Contains one 5.5 lbs. pail of blue sparkle skimmer tabs for swimming pools...
