HTH® Blue Sparkle® Skimmer Tabs, 5.5 lbs.

Keep your indoor or outdoor pool clean and clear with HTH® Blue Sparkle® Skimmer Tabs.


About This Item

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 HTH® Blue Sparkle® Skimmer Tab(s). Place skimmer tab in the empty skimmer basket. Use one tab of the product per 10,000 gallons of pool water. After one 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-pound pail of HTH® Blue Sparkle® Skimmer Tabs for swimming pools

No Cyanuric Acid

Excessive cyanuric acid (CYA) levels in pool water can render the chlorine ineffective. Blue Sparkle Skimmer Tabs are non-stabilized (contains no CYA) and will not cause overstabilization.

How to Use HTH® Blue Sparkle® Skimmer Tabs

1. Test and Balance

Dip an HTH® 6-Way Test Strip (sold separately) into the water to measure total alkalinity, pH, free available chlorine (FAC), calcium hardness, and stabilizer or cyanuric acid (CYA). Balance water and adjust alkalinity and pH levels, where necessary.
