Clorox® Pool&Spa™ Shock XTRABLUE® Plus, Kills Bacteria & Algae in Swimming Pools, Swim-Ready in 15 Minutes, (12-Pack), Granular

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!”

We've been purchasing Clorox XTRABLUE Plus for a couple of years now. It is a great chorine pack, but it includes other chemicals to keep your pool clean and clear. They claim it kills Bacteria & Algae in Swimming Pools, Swim-Ready in 15 Minutes. I don't know how effective it is for bacteria and algae. I do know it's quality chlorine. The only problem I've had with this is it contains cyanuric acid. Along with 3" chlorine tabs, which also contain CYA, it can boost the CYA levels in the pool which can lead to chemical imbalances.

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

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!!! 💙

I’ve used this several times on my above-ground pool and it works well. It helps clear the water up quickly and is easy to use. Always keep a few bags on hand during pool season.

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!

This is the only product I use for shocking my pool. It works very quickly and it helps. Keep my pool very clear. I’m more than happy with this product.

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.
