CLOROX Pool&Spa XtraBlue Chlorinating Granules 6 lb - Fast‑Dissolving Stabilized Chlorine, Shock & Algae Control

CLOROX Pool&Spa All-in-One XtraBlue Chlorinating Granules are a fast-dissolving, stabilized chlorine formula that sanitizes, shocks, and helps prevent algae for clearer pool water.

Keep your pool water safe, clear, and inviting with a single product that combines sanitizing power and shock treatment. These blue granules are designed to dissolve quickly, maintain a longer-lasting chlorine residual due to stabilization, and tackle common water problems like bacteria and multiple types of algae. The 6-pound tub provides a convenient amount for regular maintenance or periodic shock treatments, and works alongside pool testing tools or the Clorox Pool app to fine-tune dosing.

How quickly will XtraBlue granules start working in my pool?

These granules are formulated to dissolve fast so chlorine becomes available to the water sooner than slower-melting tablets. You’ll see improved clarity within hours when used as directed, with sanitizing action beginning immediately upon dissolution.

• Fast-dissolving formula for rapid availability of chlorine.
• Stabilized to resist UV breakdown for a longer-lasting residual.
• Useful for both routine sanitizing and shock treatments.

Can this product prevent and treat different types of pool algae?

The XtraBlue formulation is made to control and help prevent common algae varieties, including green, mustard, and black algae, by delivering effective oxidizing and sanitizing strength. Regular application as part of a maintenance routine reduces the chance of outbreaks and supports clearer water.

• Broad-spectrum activity against green, mustard, and black algae.
• Combined sanitizing and oxidizing action helps stop algae growth.
• Works with proper filtration to clear cloudy or dull water.

How do I use the granules safely and get accurate dosing?

Follow label instructions for dosage based on pool volume and current chlorine levels; add granules to water with the pump running to help dissolve and distribute evenly. Use a test kit or the Clorox Pool app to measure sanitizer levels before and after treatment to avoid over-chlorination.

• Add granular dose to the skimmer or dissolve in a bucket of water before adding, depending on pool manufacturer guidance.
• Run the filter during and after application to circulate the sanitizer.
• Check chlorine levels with a test kit or app-recommended method to adjust dosages safely.

Will these granules help my pool’s filter and overall clarity?

By destroying organic contaminants and algae, the product makes it easier for your filter to remove suspended particles, often resulting in clearer water and more effective filtration cycles. Consistent use alongside proper filtration and pH balance improves overall pool performance.

• Removes bacteria and contaminants that burden filters.
• Helps restore clarity when paired with adequate filtration and circulation.
• Supports routine maintenance for reduced eye irritation and odor.
