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.

    • A Pool Saver — Works Fast
Size: 12 Pack
Review Image by Haley D
It works incredibly fast, especially after heavy rain, a bunch of people have been swimming, or the water is just starting to look a little cloudy or questionable. I love that you don't have to wait forever to use the pool afterward. The fact that it's swim-ready in as little as 15 minutes is a HUGE plus, especially during the summer when telling everyone they can't get in the pool for the rest of the day isn't exactly an easy sell. It's also been great for keeping algae under control. After shocking, the water looks noticeably clearer and brighter, and I haven't had to fight that stubborn green tint nearly as much. The granular formula is easy to use, and having the 12-pack is much more convenient than realizing you're out right when the pool decides to turn cloudy overnight. If you have a pool and want something straightforward that tackles bacteria, algae, and cloudy water without a ton of hassle, this is definitely worth keeping in your pool supplies. It makes maintaining clear, clean-looking water a whole lot easier. ... show more

Here’s a 5-star review in English you can use: ⭐⭐⭐⭐⭐ “This pool chlorine powder works amazingly well! It dissolves quickly and keeps my pool water crystal clear and clean. I noticed a big difference after just one use—no cloudy water, no strong odor, just fresh and balanced water. It’s easy to measure and apply, and it maintains the chlorine level perfectly. Great quality and excellent value for the price. I will definitely keep buying this product for my pool maintenance!” ... show more

    • Clorox Pool & Spa Shock Keeps My Water Crystal Clear
Size: 6 Pack
Review Image by Jenny’s Cozy Corner
I’ve been very happy with this Clorox Pool & Spa Shock. I use it regularly in my above-ground pool, and it does an excellent job keeping the water clean, clear, and properly sanitized. After treatment, the water looks noticeably brighter and clearer, and it helps prevent the cloudy water issues that can happen during hot summer weather. The granules dissolve well, and I appreciate the peace of mind knowing my pool is being properly treated. Maintaining a pool can get expensive and time-consuming, so it’s nice to have a product that works consistently without a lot of hassle. If you’re looking for a reliable pool shock to help maintain sparkling, healthy pool water throughout the season, this is definitely one I would recommend. ... show more

    • Fast-Working Shock That Beat Expensive Pool Store Brand

Used this today at 1:50 p.m. and by 3:30 p.m. the difference was incredible. The water turned noticeably bluer, clearer, and overall much cleaner in under two hours. We’ve been struggling to keep up with the heat and had been using liquid shock, and I even spent around $100 on Burnout at a pool and spa store but this Clorox® Pool&Spa™ Shock XTRABLUE® Plus works just as good, if not better. It made an immediate visible difference and my pool looks better than it has in a while. It’s also much less expensive per package than the Burnout from the pool store too! It also leaves the water smelling clean and fresh. Five stars all the way. Highly recommend and will definitely continue buying! Check out the before and after pictures, I was shocked!!! 💙 ... show more

We love clorox pool and spa. It helps maintain our pool and keep it healthy and clear. Works wonders in our pool. With kiddos we love that its hard to open but also is swimable quickly. There is a strong odor when pouring it but it is a strong chemical. But works wonders!
