CLOROX Pool&Spa 1" Chlorine Tablets 5 lb — XtraBlue 1-inch Slow‑Dissolve Stabilizer & Algae Control

Clorox Pool&Spa XtraBlue 1" chlorinating tablets are a stabilized, slow-dissolving sanitizer designed to kill bacteria and inhibit algae in small and mid-size pools.

These 1-inch tablets come in a 5 lb container and combine chlorine with a stabilizer and water-conditioners to extend residual protection from sunlight and leave water feeling smooth. Formulated for routine pool maintenance, they dissolve slowly for steady chlorine delivery and are compatible with vinyl, plaster, fiberglass, and tile surfaces. The package includes product code 29005CLX and is intended for use in floaters, automatic feeders, or skimmers designed for 1-inch tablets.

How do these tablets keep pool water safe and clear?

The tablets release a measured amount of chlorine to neutralize bacteria and organic contaminants, while a built-in stabilizer helps protect chlorine from degradation by sunlight. They also contain agents that help prevent and control common types of pool algae, reducing the need for frequent shock treatments.

• Slow-dissolve 1" tablets for steady chlorine feed
• Stabilizer (cyanuric acid) to reduce UV breakdown
• Conditioners to improve water feel and clarity
• Effective against green, mustard, and black algae types

What are the proper ways to use XtraBlue tablets in my pool?

Place tablets in a floating dispenser, in-line feeder, or tablet feeder specifically built for 1-inch chlorine tablets; avoid dropping tablets directly into the pool or skimmer for long-term use. Follow label dosing recommendations and monitor free chlorine and pH regularly to keep levels within the ideal range.

• Use a compatible floater or automatic feeder for consistent dosing
• Test chlorine and pH at least twice weekly, adjusting as needed
• Store unopened container in a cool, dry place away from sunlight
• Do not mix with other pool chemicals or let tablets accumulate in skimmer baskets

Will these tablets harm pool surfaces or equipment?

When used as directed, XtraBlue tablets are safe for most pool surfaces including vinyl liners, plaster, fiberglass, and tile. Proper dosing and regular testing help prevent corrosive conditions or scale; always avoid concentrated contact between undissolved tablets and pool materials or equipment.

• Safe on common pool finishes with correct dilution
• Avoid placing undissolved tablets directly on liners or surfaces
• Rinse hands after handling and use protective gloves if needed
• Follow equipment manufacturer guidance for in-line feeders

How can I manage dosing and troubleshoot problems easily?

Combine regular water testing with the Clorox Pool App for tailored guidance on dosing, troubleshooting, and product recommendations. The app helps interpret test results and suggests how many tablets or additional treatments are needed to restore proper chemistry.

• Use test strips or kits to measure free chlorine and pH
• Consult the Clorox Pool App for personalized dosing tips
• Increase circulation and filtration after adding tablets for even distribution
• Shock the pool when heavy bather load or persistent algae appears
