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.

Oh my God I was so bad this year - We ran out of chlorine during the winter... Which is usually fine because algae doesn't bloom in the winter I've noticed.... But here we are going into spring or the desert so the days are already up at like 80 to 85° so it started blooming! We've had it covered all winter with like one of those blue bubble covers - so I'm going to tell you the right way to use the shock because I see some people in the reviews complaining it's not working. Step one BRUSH YOUR POOL! It's going to be gross because your pool is basically a nasty little swamp pond and it's going to be stinky and probably slimy but brush it and loosen up all that nasty algae. Step two Do your best to skim it as much as you can especially around the filter inlets - Make sure your pool pump is running during brushing and skimming. Step three SHOCK YOUR POOL! The instructions are super clear and actually tell you to do the above step number one lol I've shocked my pool before and it not work because I didn't brush it and loosen up all the crap and I was trying to get rid of. No I'm not doing anything other than that to prep the pool - I'm not balancing pH or adding any chemicals or whatever it's just nasty pond water getting agitated. In my photos you'll see in just 10 minutes the shock is already starting to change the color of the pool - I know I was shocked too. Then there's the photo of it getting more clear and that's at least 2 hours after the shock. I used a whole bag even though that's way too much for our pool because I needed to use the big guns and get it taken care of. I'll update my review when I've got the more photos to share I'm actually in the process of doing it right now those photos above are from like a couple hours before Im writing this review. ... show more
