A must have!

Would Recommend

[This review was collected as part of a promotion.] We absolutely have to have shock at all times! I usually shock our pool about once a week. We live in an area where there many trees so our pool gets dirty pretty quickly. I paid this shock with clarifier and a pool vacuum and it gets back to new in no time at all!

Great Product

Would Recommend

[This review was collected as part of a promotion.] I love how after having a large group over for a pool party that we used this product before to make sure our pool would be ready for the increased number. It was easy to use and help put our minds at ease knowing we had done all we needed to make sure we were ready.

Easy to use containers

Would Recommend

[This review was collected as part of a promotion.] So often shock comes in this bully container and it’s hard to measure let alone pour in my pool. These easy to hold and pour 1lb containers make taking care of my pool easy and less physically straining. I am really glad I came across these. They will be my go to moving forward.

Would Recommend

[This review was collected as part of a promotion.] We wanted to go swim for the last few weeks left for winter and I wanted to try a new shock treatment for the pool.

No cyanuric acid, big plus for me.

Would Recommend

[This review was collected as part of a promotion.] Longer use of most chlorine products will cause the development of cyanuric acid, which is a problem for a lot of reasons. I really enjoy the benefits of this shock, as it clears and maintains the water beautifully in our above ground pool, but also does so without adding any or creating any acid byproduct. This is the game changer for me, to have a clean pool but also one that is healthy and remains so to swim in!

Perfect shock packs!

Would Recommend

[This review was collected as part of a promotion.] I will be buying more of these because I can tell it's good quality shock. Any hint of cloudiness and I sprinkle a bag in the pool and the next morning the water is back to clear! Better quality shock than the cheapies out there. Don't waste your money on those!

Must have pool care

Would Recommend

[This review was collected as part of a promotion.] I love this shock. It is very easy to use and the response that the pool water has to it is so quick! I use this shock if my chlorination level is too low and I know that this will rectify it every time. Definitely the best shock that I’ve used for pool upkeep.

Works great

Would Recommend

[This review was collected as part of a promotion.] When your pool gets really icky, this stuff will help get it back on track. This is the brand I always turn to. The directions are easy to follow and I'm always pleased with the results. I know it's the end of pool season, but pick up some of this and put it away for next year. You'll be glad you did when you go to open your pool.

Got rid of the green in 24 hours

Would Recommend

[This review was collected as part of a promotion.] I purchased this product along with some others after having our pool's water tested and found out the levels in certain areas where off. Before agreeing to purchase the chemicals from the pool center I decided to try HTH brand. What I purchased was 1/3 the price vs the store's brand. I wasn't sure how this would stack up, you know the old saying you get what you pay, well I'm happy to say that this product worked perfectly compared to the stor...

Works great

[This review was collected as part of a promotion.] This shock treatment works as expected! It took care of my greening water in under 24 hours. There was some white residie left behind, but pretty sure thats normal. With some stirring the pump took care of it. Really happy with the results. So glad I got the 6'pack.

Works as advertised!

Would Recommend

[This review was collected as part of a promotion.] It's pool shock! And it works! What more could you ask for? I had a little bit of cloudy water before I added a bag and 30 mins later, it had cleared right up! Love it! I would recommend this product to everyone with a pool.

Clear sparkling water

Would Recommend

[This review was collected as part of a promotion.] Just tried these out over the weekend. We'd had a fair amount of rain and the water was starting to look a bit murky. It had cleared right up a couple of hours after adding the shock, and looked noticeably clearer and more sparkling than after using my usual brand of shock. It brought the chlorine levels up a considerable amount, too, so should keep the green at bay.

Works Great!

Would Recommend

[This review was collected as part of a promotion.] I tried out the HTH® Pool Care Shock Advanced and it works great. My father-in-law has an in-ground pool and he was very sick. I bought this among others to help him get his pool back in order. I have never used these products before. The instructions were easy to understand, and I was able to clear up the pool and get it back in order. I highly recommend this and would definitely buy again.

Very Potent

Would Recommend

[This review was collected as part of a promotion.] This stuff works great! Though one should definitely proceed with caution, and handle with care. Be sure to wear gloves and sometimes a mask when handling these powdered chemicals. I'm also very mindful about hosing the entire pool area down after sifting the product around, so that neither people nor pets will sniff it in... And, I usually rinse my shoes off and throw whatever pants I'm wearing directly in the washing machine, then wash my han...
