Description

Enjoying your beautiful pool just got easier with the convenience and power of Clorox Pool&Spa Shock XtraBlue2. Each bag treats 12,000 gallons of water to clear cloudy, smelly water. This fast-dissolving pool shock kills bacteria and removes swimmer contaminants while helping control algae growth. It will not bleach your liner or affect your water's pH level like other brands. Shock your pool weekly and after pool parties and severe weather to remove contaminants, destroy odors, and keep the water clear. No premixing is required and dissolves fast! Shock day or night! Save time when shocking, as our XtraBlue Shock2 will treat 12,000 gallons of water and you can swim in 15 minutes! Always apply according to label directions. For best results, add to the deepest end of the pool with the filter running. Circulating pool water when applying chemicals helps disperse chemicals throughout the pool for maximum coverage. The best pool shock on the market, use once a week during your weekly maintenance program. Pair with the Clorox Pool app and XtraBlue Chlorinating Tablets for best results.

    • DEPENDABLE pool care!
Size: 6 Pack
I recently used Clorox Pool&Spa Shock XTRABLUE Plus in my pool, and I’m seriously impressed. It killed the bacteria and algae fast, leaving the water crystal clear and sparkling. I love that it works so quickly—I added it in the evening, and by the next morning, the pool looked amazing. It’s easy to use and dissolves well without leaving any residue or cloudiness. The water feels clean and safe, which is a huge relief when swimming with family and friends. I also appreciate that it’s a reliable brand I can trust for pool maintenance. If you want a simple, effective solution for keeping your pool bacteria- and algae-free, this shock treatment is definitely worth it. Highly recommend for anyone looking for fast, dependable pool care! ... show more

    • Easy
Size: 12 Pack
This is the only thing I put in my pool, keeps it clean and clear and it's worked for the last few years. We keep it open all winter and add about 1 a month then when the temp gets up to about 65 we just add about 4 at once then 1 or sometimes 2 a week all summer.

    • Shocker!
Size: 36 Pack
Great product for the pool! Dissolves quickly. Price is right. Definitely kills bacteria. Helps keep pool clean. Hubby likes to do polar plunge. We keep our pool open during most of the winter. This product still works in freezing temps.

    • Good product, stabilized form of "chlorine" , has upside and downside but i like it. See video.
Size: 12 Pack
The media could not be loaded. i chose this over sodium hypochlorite shock for my swimming pool. Sodium dichloro-s-triazinetrione (often called "Dichlor" or simply "granular chlorine") is a stabilized, fast-dissolving, and pH-neutral chlorine sanitizer (55-63% available chlorine) designed for maintaining sanitization levels in swimming pools, hot tubs, and spas. It is highly effective because it contains cyanuric acid (CYA), which protects the chlorine from sun degradation, making it more long-lasting than un stabilized liquid bleach. I have used this in "tablets" used in my pool and have not had an issue with "chlorine lock" but do monitor for that. It's granular, you distribute with the pool running, do not put into the feeder. It has a higher chemical content that regular bleach, i like the 12 bag size of this offering and have used it before. There is not an ideal solution and i try to keep the chemicals balanced so i am not shocking the pool weekly. ... show more

This product is great. I use this product on my pool every week. Works just as great as the shocks you get from a pool store and you're not paying the expensive price. Very economical. It dissolves quickly and within an hour to two hours it safe to swim. It leaves my pool look crystal clear. It kills all the bacteria and algae build up. I do recommend the product to any one ... show more
