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. ... show more

    • This pool shock seems to work a lot better than others
Size: 6 Pack Style: Regular Shock
I’ve tried cheaper brands and some more expensive brands but this stuff seems to work very well. Ordering from Amazon is a little cheaper and more convenient than going to the pool supply store to purchase. Not sure what else I can say I mean it’s Poole shock! But it is easy to use. Just cut the bag open and sprinkle it in your pool. Just don’t do it on a windy day or it will blow all over the place. ... show more

    • Works great!

Review Image by Diana Diana
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. ... show more

    • It worked for my stock tank pool!
Size: 6 Pack Style: Advanced Shock
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!) ... show more

    • Quality chlorine shock for pools
Size: 6 Pack Style: Advanced Shock
This shock works great and is my preferred brand. The multiple packages are great so I don’t have to have a large amount of open chlorine. Works great to keep algae out and keeps the water levels consistent. Would recommend

    • Good price, works great!
Size: 1 Pack Style: Regular Shock
This product helped the clarity, the chlorine levels. I shock my pool twice a week and every-time I test my pool it comes back great! I have a 1,700 gallon pool so I get several uses out of this bag.
