Clorox Pool&Spa XtraBlue 3 Chlorinating Tablets 25 LB - Long Lasting

Our review of Clorox Pool&Spa XtraBlue 3 chlorine tablets finds them best suited for homeowners and pool caretakers who prioritize clear, silky water and reliable algae control. The single biggest reason to buy is straightforward: these tablets both kill harmful bacteria and prevent all types of pool algae while adding a conditioner that leaves water feeling smooth. In real use they simplify weekly maintenance by offering a measured, stabilized chlorine source that also protects equipment from corrosion and reduces scale and stains.

Key Features

• Kills bacteria: Formulated to eliminate harmful bacteria to keep pool water sanitary and safe for swimmers.
• Stops algae: Prevents and treats green, mustard, and black algae so water stays clearer for longer stretches between shocks.
• Sunlight protection: Contains a chlorine stabilizer that extends effective chlorine life under sunlight, reducing frequent dosing.
• Silky water feel: Includes water conditioners that create a smooth, comfortable swim without harsh chlorine sensation.
• Surface safe: Suitable for vinyl, plaster, fiberglass, and tile so it can be used across common residential pool finishes.
• Simple dosing guidance: Manufacturer recommends applying 2 tablets per week per 10,000 gallons, making routine upkeep easy to plan.

Who It's For

This product is aimed at residential pool owners and caretakers who want a dependable, low-effort chlorination method that also addresses algae and equipment protection. It is especially useful for those with medium to large pools who prefer weekly tablet dosing and a stabilized chlorine that resists sun degradation.

Those who need instant shock-level chlorine for heavy contamination or who prefer non-chlorine sanitizers should look elsewhere. Also, users who require specialized dosing systems should confirm tablet compatibility with their specific floaters or feeders, since tablet breakage has been reported occasionally by some customers.
