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.

  • Crystal Clear Pool Magic – XTRABLUE® Plus Delivers Every Time!
Size: 12 Pack
I've been using Clorox® Pool&Spa™ Shock XTRABLUE® Plus for my above-ground pool this summer, and it's an absolute game-changer! One treatment after a busy weekend of family splashes, and my water went from slightly cloudy to sparkling blue overnight. It truly lives up to its name – the XTRABLUE® formula not only kills off bacteria and algae but leaves the pool looking professionally maintained without any harsh chemical smell lingering. What I love most is how easy it is to use: just dissolve in a bucket of water, pour it in, and run the filter for a few hours. No fuss, no measuring headaches. My pool stays balanced longer between shocks, saving me time and money. We've had zero algae blooms or funky water issues, even during that heatwave last month. If you're tired of green nightmares or constant scrubbing, this is your hero product. Highly recommend for any pool owner – it's reliable, effective, and keeps the fun uninterrupted! ... show more

  • Concentrated so economical to use in hot tubs
Size: 6 Pack
Bought for my hot tub. A little goes a long way since it’s concentrated. Makes the price a great deal as opposed to buying the stuff for hot tubs. I just weighed the powder and did the math to figure out how much to use for the amount of gallons in my hot tub.

  • 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

  • Works well, powder is difficult
Size: 12 Pack
Works very well. Bags are a bit difficult to tear so you will need scissors for easier opening. I think the liquid is a bit easier as the powder does leave a cloud in the air, so wear a mask!

  • GREAT PRODUCT!!!

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
