HTH 52026 Super Shock Treatment Swimming Pool Chlorine Cleaner, 1 lb (Pack of 12)
[{'review_meta': 'Reviewed in the United States on July 14, 2020', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "I have experimented with various types and brands of shock for my pool and this one provides the most value for the money.\nI've tried the large buckets of shock that have 73% Cal Hypo (the active ingredient in sanitizing your pool). They are very heavy (50%) and I always used more than necessary with the scoop. I've also tried other bags of shock with 68% Cal Hypo. Oddly, they were rated to treat 10,000 gallons per bag.\n\nThese bags contain 56.44% Cal Hypo and are rated to treat 13,500 gallons. I have found them to be just as effective as the more expensive bags. I have a 15,000 gallon pool and only use 1 pack about every 4 days depending on pool usage. That's the same rate I used with others without getting any algae buildup.\n\nOne more tip: I found the effectiveness improved when I started mixing the shock in a bucket of water first. They tell you to do that to protect the liner but I've also found in roughly similar conditions that the Free Chlorine lasted longer when I pre-mixed it."}, {'review_meta': 'Reviewed in the United States on June 3, 2020', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "The 12 package portions is perfect for my 20x40 9' pool. One every month and/or just before a decent sized pool party and you're good to go. No measuring and not having to worry about the environment they are stored in. Definitely will buy it again."}, {'review_meta': 'Reviewed in the United States on June 18, 2021', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'We have a 24 x 52 round above ground pool.. and have tried different types of shock including liquid chlorine. But of all of them, HTH Super Shock has been the best. I am a repeat buyer of this shock. It lasts and I only have to shock the pool once or twice a month. PLUS the 12 pound bundle is really a money saver.'}, {'review_meta': 'Reviewed in the United States on July 25, 2022', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "I used to use this product often. I had a recurring subscription through Amazon. One time I used it and later noticed a HUGE stain in my pool shortly after. I didn't know the stain was a reaction from this product immediately. I balanced my pool, bought stain removal (spending spending spending), followed all instructions to the T. EVENTUALLY, I got the stain to go away after a lot of time, money, effort, and frustration. So fast fwd. Next time I had to shock my pool, WITHIN MINUTES, it stain my pool again. But not just in that spot, literally in every spot the product touched the floor of my inground pool. I sprinkle it SO lightly, I literally walk around the pool like 3 or 4 times and salt and pepper it in just to try and prevent it from accumulating anywhere on the bottom of the pool. Alas, it does not matter. So I cancelled my subscription after having used this product for years. My feeling is that with the rise in costs on chlorine tablets, HTC seems to have taken the low road and changed the ingredients comprising their product. Nevertheless as a consumer, I will waste no more time or money on it. I will keep my pool balanced and stain free using other brands and products."}, {'review_meta': 'Reviewed in the United States on June 15, 2020', 'review_star': 'a-icon a-icon-star a-star-1 review-rating', 'review_body': 'I was unaware this product adds material that will raise the PH of a pool. I needed mine to go lower. I thought I was buying only granular chlorine. Not so. Check with your local pool store before adding this product to your pool and find a store that can accurately measure your pool chemistry. I will no longer be using this product.'}, {'review_meta': 'Reviewed in the United States on August 9, 2021', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'This stuff don\'t do as good as it use too\nLooks like I\'ll be going to an actual pool supply store from now on . and the price increases for a Wal-Mart brand shock that don\'t seem to work at all anymore is insane. I have a 18\' 52" round pool and I put almost twice as much as needed and the pool actually turned green .its almost like I purchased bags of green algae instead .'}, {'review_meta': 'Reviewed in the United States on June 3, 2021', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'I have a 20K gallon pool and have tried many different brands of shock over the years. Many brands leave a thin layer of undissolved powder on the top of the water when dumped into the pool. HTH dissolves almost completely and does a great job keeping my pool sanitized. Five stars!'}, {'review_meta': 'Reviewed in the United States on November 19, 2020', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'If you have black mold in your pool, this will take care of it . With the pool pump off, sprinkle this, lightly, directly over the mold area. Let it sit undisturbed for a 30 to 60 minutes, then lightly brush part of the area and see if\nis loose. Brush the area and repeat as required.'}, {'review_meta': 'Reviewed in the United States on August 14, 2020', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'I have a Costco-sized splash pool that my son had termed "the swamp." Because we live in a desert, I really didn\'t want to waste the hundreds of gallons of water to refill it, so purchased this. I poured in an entire pouch, and the pool was clean by the second day (it had a LOT of work to do). That first treatment lasted about 3 weeks, and then I used a half a packet for the second treatment, and it worked great again. This will last me all summer, keeping the water clean. I use a similar product in my laboratory to keep water baths clean, so I know it works!'}, {'review_meta': 'Reviewed in the United States on September 16, 2020', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'I wish I had a before picture to compare with the after. We went away for a few days and forgot to treat the pool first. We came back to a pool that was completely green. I have an inground pool and I added four bags of shock yesterday afternoon. It’s now 7 AM and the pool is completely blue, crystal clear and see-through. Amazing!!!!!!!'}]
