    The HTH 52036 Swimming Pool Care Shock Advanced is outstanding for pool maintenance. This 6-pack delivers effective results quickly, clearing cloudy water and combating algae. The shock dissolves easily and doesn’t leave residue, making it user-friendly. After one treatment, my pool stayed crystal clear even with rainwater, which is impressive. The 6-pack offers great value, as it lasts longer than many other products. It’s suitable for all pool types, whether above-ground or in-ground. Overall, this pool shock is reliable and efficient, providing excellent results with minimal effort. Highly recommended for anyone seeking a high-quality solution for maintaining pristine pool water.

    4.0 out of 5 stars It worked for my stock tank pool!
    Reviewed in the United States on September 3, 2024
    The product worked, however there were no instructions on the package on how much to use for smaller pools... The package indicated it would treat a 13,500 pool, which was WAY larger than my 700-gallon stock tank pool, thus the four-star rating. I had to do some calculations and started out with a tablespoon, which after 24 hours was not enough. I added more which was still not enough after 24 hours. I finally, ended up using 1/3 of the bag which did the trick. My stock tank pool's interior has pond shield on it and there doesn't appear to be any damage to it. I did have to run my Intex pump with filter for over 20 hours (changing the filter three times during this period) as even though the green was gone, the water was still very cloudy. The box contains six bags which should be enough to last me many years as we rarely get a lot of rain during the summer (like we just did which caused the pool to go green!)

    5.0 out of 5 stars A Chlorine-Free Miracle
    Reviewed in the United States on August 3, 2024
    I was skeptical at first about a chlorine-free product claiming to boost chlorine levels, but HTH 52031 Swimming Pool Care Shock completely blew me away. This summer, I used this product exclusively and didn't have to touch a single drop of chlorine!

    It’s incredibly easy to use and has made pool maintenance a breeze. I’m amazed at how effectively it keeps my pool sparkling clean and algae-free. Plus, it's incredibly budget-friendly compared to traditional chlorine products. If you're looking for a safe, effective, and affordable way to maintain your pool, I highly recommend giving HTH 52031 a try.

    Easy to use. Our pool was starting to show signs of algae growth along the pool walls so my husband needed to shock it. We’ve purchased shock through our local Lowe’s but this time decided to go with Amazon as we felt like it was at a lower rate which is a win for us. We shock our 10,000 gallon pool weekly running the pump for 12 hours as we add other chemicals too. It leaves the water sparkling clean and always makes me want to jump in the following day because the water looks so nice. I say that it last about a week before having to re-shock or depending on how often pool is used.

    5.0 out of 5 stars Effective Shocking without raising cyanuric acid
    Reviewed in the United States on November 25, 2024
    This shock works great. Best part it that is does not raise cyanuric acid. It's an issue I've had with other shocks that when it raises cyanuric acid the regular chlorine is not effective.
