Ratings & Reviews for HTH 16-oz Cal Hypo Pool Shock

Perfect shock packs!

[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

[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

[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

[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...

[This review was collected as part of a promotion.] This HTH Pool Shock works just like it is supposed to, it cleared my pool up overnight! From cloudy and green to crystal clear and blue! Definitely a product I would recommend to anyone that owns a pool!

Works Great!!!

[This review was collected as part of a promotion.] I received this a few days ago and it works great. We put the shock in our pool Saturday morning and by the afternoon hours, my pool water looked clear as day. They pool care shock advanced treatment works fast, and very well. I am very happy with the results and will use again.

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!

[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

[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.

Shock works great!

[This review was collected as part of a promotion.] I love this shock because it makes my pool look beautiful and a gorgeous blue color. Easy to use, does not clump up. Spreads around the whole pool quickly. No cloudiness at all. I definitely recommend this shock to others. I will definitely use this product again.

Works Great!

[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

[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...

Works great!

[This review was collected as part of a promotion.] I absolutely love HTH products! This pool care shock is top notch! It clears the water fast and stays clear. It gets rid of the algae and keeps my pool clean. It's great for weekly treatments and after rain. Highly recommend!

Fantastic

[This review was collected as part of a promotion.] Easy to use just distribute the amount you need in the pool and watch it take care of any Ickes. Works just a described. Easy to follow directions. Perfectly packaged to store easilyI will definitely stock up and keep on hand as we really don’t have much of winter here in Florida.

Awesome!

[This review was collected as part of a promotion.] I use this to open my pool and again throughout the season if needed. It works great and also gets my pool cleared up quickly. The HTH family of products are all I use to keep my pool looking crystal clear. They are always easy to find in my local stores. A great value and always a great products!

Excellent at keeping pool water clear

[This review was collected as part of a promotion.] It definitely works at keeping pool water clear for a very long time. We just have to keep up with maintaining and cleaning leaves out of the pool by skimming them. Helps to have chlorine tabs as well.

Great Value

[This review was collected as part of a promotion.] I loved the HTH Pool Care Shock Advanced, came with several packages in one convenient bag, we poured it in the pool and it worked super fast especially after a good rain. Easy to handle a smaller nag then a tub and you have the exact measurement you need ready to pour in. Can be easily found in any store you are showing in with is a plus...

Special shock

[This review was collected as part of a promotion.] I have been using this product for the last month. I live in Arizona so the summer months are really difficult to maintain a pool. Extremely easy to use and the packaging is awesome. No allege or any other problems with our pool this year.
