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

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 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.

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

Good but 1 bag is enough, not even "upto" 12,000gallon. I use 1 bag for 10,000g pool, not enough then next day (after 24hrs) I added 1 more bag. It works! Still, there is a combination of chemicals to make your pool perfectly, not just shock xtra blue itself. Recommended!

This stuff is amazing! Makes our pool water crystal clear within hours. Just throw it in at night and the next morning you wake up to resort looking water. Cheaper here than at stores.

i chose this over sodium hypochlorite shock for my swimming pool. Sodium dichloro-s-triazinetrione (often called "Dichlor" or simply "granular chlorine") is a stabilized, fast-dissolving, and pH-neutral chlorine sanitizer (55-63% available chlorine) designed for maintaining sanitization levels in swimming pools, hot tubs, and spas. It is highly effective because it contains cyanuric acid (CYA), which protects the chlorine from sun degradation, making it more long-lasting than un stabilized liquid bleach. I have used this in "tablets" used in my pool and have not had an issue with "chlorine lock" but do monitor for that. It's granular, you distribute with the pool running, do not put into the feeder. It has a higher chemical content that regular bleach, i like the 12 bag size of this offering and have used it before. There is not an ideal solution and i try to keep the chemicals balanced so i am not shocking the pool weekly.

Clorox is my very favorite for all pool needs. Really does the job.

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.
