Clorox® Pool&Spa™ Shock XTRABLUE® Plus, Kills Bacteria & Algae in Swimming Pools, Swim-Ready in 15 Minutes, (6-Pack)

Great dichlor shock. Add in at night. In the morning w filter pump running water is crystal clear. I use this about once a week when it’s very hot out in summer. It’s great when u don’t want to increase your chlorine levels. It also appears to add some CYA which is a nice buffer for your chlorine so the sun won’t eat it up. Great product. Only thing to remember is to add on a day when it’s not windy. On a nice still day just walk around the pool and put it in right from the bag. No mixing.

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!”

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.

This stuff is amazing. Always keeps my water crystal clear. I shock once a week

Works fast for a clear, clean pool with very little down time. No heavy chemical smell unlike other similar options.

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!

Great product. Lives up to the Clorox brand name. My inground pool water is beyond crystal clear. Doesn’t not burn off in high temperatures or strong sunlight. Well worth the money. I have switched over all my pool products go Clorox.

Arrived very quick and in perfectly new condition as expected. This 6n1 was a great value as I got it for what I normally pay for the 4n1. These are great pool chemicals and keeps me from having any algae issues. Definitely recommend.
