HTH 1" Chlorine Tablet 1.5 lb | for Pool Sanitizing

Formulated to deliver slow-dissolving, continuous chlorine sanitization, HTH 42049 Pool Care 1-inch Chlorine Tabs are engineered for above ground, small, pop-up, and vinyl-lined pools as well as saltwater pool systems. Each tablet is sun-protected with built-in stabilizer that resists UV degradation, extending active chlorine life and providing a steady sanitizer release designed to last up to one week per dose. An added clarifier works alongside the chlorine to keep pool water crystal clear by breaking down body oils, sunscreens, lotions, and organic buildup that can cloud water between maintenance sessions. The tabs are used simply by dropping them into a floater, skimmer basket, or chemical feeder, where they continue working without daily hands-on attention from the pool owner. For best results, chlorine levels should be maintained between 1 and 4 ppm using HTH 6-Way Test Strips twice weekly. The 1.5-pound container is an economical entry-level supply suited to smaller pools, seasonal use, or as a convenient top-off purchase between larger buys.

Highlights

• Week-Long Sanitizer Release Per Dose: The slow-dissolve formulation in each 1-inch tab is engineered to release chlorine gradually over up to a full week, providing continuous sanitizer coverage between maintenance sessions and reducing the daily chemical adjustments that pool owners running fast-dissolve products often have to make throughout the swim season.
• Stabilized Chlorine for UV Resistance: Built-in stabilizer protects the active chlorine from breaking down under direct sunlight, keeping a higher percentage of the sanitizer active in the water for longer periods and lowering the total amount of chemical the pool owner needs to add to hold a consistent ppm reading through hot, sunny weather.
• Clarifier Fights Cloudy Water: An added clarifier works in the pool alongside the chlorine to break down body oils, sunscreens, lotions, and other organic material that cloud pool water between cleanings, helping the water stay visibly clearer during days of heavy swimmer use or after weekend gatherings.
• Works Across Pool Types and Feeders: The HTH 42049 tabs are designed for use in above ground pools, pop-up pools, small in-ground pools, vinyl-lined pools, and saltwater pool systems, and they can be delivered via chlorine floaters, skimmer baskets, or automatic chemical feeders, giving the pool owner flexibility to match the tabs to the equipment already in place.
• 1.5-Pound Container for Small Pools: The 1.5-pound container size makes the HTH 42049 an economical, entry-level supply option suited to smaller pools, seasonal-use pool owners, or as a top-off between larger tab purchases, and HTH recommends holding chlorine levels between 1 and 4 ppm for safe, clear swimming water throughout the swim season.
