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!

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.

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

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.
