[This review was collected as part of a promotion.] After weeks of dreary gloomy rainy weather my pool turned 50 shades of green- ugh. Not shocking weekly as recommended, not even keeping chlorine tabs in the floater because I just didn't care since we weren't able to swim anyway, big summer bummer set in. Finally the sun appeared and everyone wants to dip their toes again so in went the HTH Shock Advanced (following the instructions on the package) with fingers crossed and swimsuits ready. Our ...

Keeps the Pool Crystal Clear!

[This review was collected as part of a promotion.] The HTH Shock Advanced 1lb packs are a great shock to keep your pool clear and ready for use all year. One package of shock spread around the pool once a week is all it takes. The granules dissolve as desired without leaving any sitting on the bottom of the pool if it is evenly spread. One package should cover approximately 13,000 gallons. However, one per week keeps my 18,000 gallon pool along with tablets keeps it clear with minimal effor...

[This review was collected as part of a promotion.] I have been using this for the last month. A bag lasts about 2.5 weeks before I need to use another one. I love that it helps keep my pool clear and clean. It is an easy cut top which makes pouring it into the pool super easy and clean up is a breeze.

Nice portioned bags

Would Recommend

[This review was collected as part of a promotion.] This 6 pack makes it really easy to remember to add to the pool, this makes the clarity of the pool incredible. I will continue to use this brand and portioned out product. It works perfectly and leaves the pool balanced unlike some other shocks I have used in the past. If you maintain proper balance, you use less chemicals.

Only brand I use

Would Recommend

[This review was collected as part of a promotion.] Great shock brand. Easy to find and use. I have a 5,200 gallon above ground pool, and I use one bag a week to keep my pool clean and blue. These granules dissolve quickly, unlike some other brands that clump and stick to the bottom of the pool. This type has other chemicals in it to keep the pool balanced and algae free longer keeping it safer to use. I love the brand and will keep using it as long as we have the pool.
