Clear pool

Would Recommend

[This review was collected as part of a promotion.] Very easy to use, cleared pool and did not cause any skin irritation. Our pool was a little murky from too many kids with sunscreen, we used this product and our pool cleared quickly. I am glad I used it!

Shock rocks

Would Recommend

[This review was collected as part of a promotion.] The pool was looking a little lousy post all these rain storms we’ve been having. It was pretty cloudy and looked slightly discolored, popped this shock in and it looks great the next day. Much clearer and ready for us to jump in and enjoy.

Shock for pools

Would Recommend

[This review was collected as part of a promotion.] I got this bag comes with six individual bags of shock. Instructions are very easy to understand so you know how much to use in your pool.

Incredible

Would Recommend

[This review was collected as part of a promotion.] Our pool is under a bunch of trees in the back yard. We have to clean it every day because all the nuts,leaves and the insane amount of pollen that gets in the water. It's awful and so hard to keep useable. We switched brands and found this stuff,which, honestly,is the best thing we ever did. I cannot tell you how FAST this stuff works and how clear the water is after. Premium stuff!

Easy to use pool shock!

Would Recommend

[This review was collected as part of a promotion.] I have the Latham 16' x 35' Olympia saltwater pool that is around 15,250 gallons. First, I like that this shock is safe for saltwater. Second, I typically start with 1 packet of this shock as 2 packets is sometimes overkill. The water in my pool is typically pretty clear, but when I start to see any type of speckle in the water, I first use a package of this shock to clear things up and to be honest, I've never had to use a second package. This...

Easy to Use!

Would Recommend

[This review was collected as part of a promotion.] This pool shock product really works! It's very easy to use and straight forward. It gets rid of algea and raises the chlorine in one simple step. I just add a little at a time to my skimmer basket until I've used an entire packet. One packet treats my 7000 gallon pool. It leaves my pool looking sparkly clear. I love that it chlorinates and clarifies while also keeping algae in check. This product includes six individual treatments and is...

Shocked

[This review was collected as part of a promotion.] This product was a great remedy for getting our pool clean and clean and ready for fun! It ate the slimy algae quickly. I was in a panic to get the pool ready because of family flying in to visit over the weekend and am thankful that this product worked fast!

Perfect

Would Recommend

[This review was collected as part of a promotion.] I needed shock and got to use this brand. I like the fact that they are in individual packs which makes it easier to treat my pool. It works pretty fast when you need to shock your pool. I would definitely pick these up again.

Crystal clear water

Would Recommend

[This review was collected as part of a promotion.] Tried HTH pool shock for the first time ever. We have used others and have never seen the results we received with HTH. We followed the directions as directed on the package and both my husband and myself were thrilled with the results. Beautiful crystal clear water. No smells. You could see detail to the bottom of the pool. Excellent choice.

Clears the pool right up!

Would Recommend

[This review was collected as part of a promotion.] We love this brand of shock for our pool! It helps clear the water up fairly quickly with ease! All we have to do is dump it in and let it set. We don’t have to do it as often either because it works so well.

Does the job!

Would Recommend

[This review was collected as part of a promotion.] Used the HTH Pool Care Shock advanced and it was very easy to use and quite effective. We typically apply the shock treatment once a week which seems to be sufficient. It’s very reassuring to know that when my family goes for a swim, they are swimming in clean water!

Sparkling pool!

Would Recommend

[This review was collected as part of a promotion.] HTH Shock Advanced has helped keep algae out of my pool even when the pool water temperature reached 90 degrees this summer! With so many hot days, my chlorinator ran out a couple of times before I noticed. The shock cleared the water quickly. I make sure ph and alkalinity are with in recommended range and then put it in in the evening and make sure the pumps run a few hours. The next day, it is ready for swimming!

Great size

Would Recommend

[This review was collected as part of a promotion.] This product is great to have on hand for regular maintenance and keeping the pool crystal clear. Even though pool season is almost over we still have some days of summer to swim in our pool. This keeps the pool levels stable.

Easy to use!

[This review was collected as part of a promotion.] I live in the South where weeks of rain can ruin the Ph of our above ground pool. This shock kit is easy to use and easy to get my pool back to swimming condition. Along with some of the other products in the HTH line, this is one of my go to to keep my kids swimming when weather permits

Wonderful product

Would Recommend

[This review was collected as part of a promotion.] I use this HTH Shock advanced product in my 40,000 gallon salt water pool all the time. As soon as we see any sign of algae, we toss in two to three 1 lb bags and all is crystal clear again within a few hours. I love that it does not contain Cyanuric acid, so it is easier on your eyes and skin. So easy to use. Best to keep a min of 6 1 lb bags on hand all summer long!
