Why selected: High purity Tri-Chlor formulation aims at consistent sanitation across season-long use. The 3-inch size fits most standard feeders and floats, making maintenance straightforward.
Caution: Slow-dissolving tablets may require occasional feeder adjustments to prevent over-stabilization in very hot climates.
TABIT 25 Pounds 3 Inch Chlorinating Tablets

Buying Guide: Key Purchase Considerations
- Pool size and volume: Larger pools benefit from bulk-pack tablets with slow-release formulas; smaller pools can use standard 3-inch tablets without over-stabilizing the water.
- Dispenser compatibility: Check whether your feeder, skimmer, or floater accepts 3-inch tablets and if you need additional stabilization.
- Stabilized vs. unstabilized: Stabilized (with cyanuric acid) helps protect chlorine from UV degradation but can complicate chlorine management in very sunny climates. Unstabilized variants dissolve faster and may require more frequent dosing.
- Water balance: Regularly test and maintain pH, alkalinity, and calcium hardness. Chlorine tablets should be used in conjunction with a balanced water chemistry plan to avoid corrosion or scale.
- Packaging and storage: Bulk options save money but require proper storage. Individual-wrapped tablets reduce dust and odor exposure, important for households with sensitive individuals.
- Safety and handling: Wear gloves when handling tablets. Store away from children and pets, and keep tablets dry to preserve potency.
