Ratings & Reviews for HTH 12 -Pack 16-oz Cal Hypo Pool Shock

Resonably Priced

It was easy to order online & pick up at the store. It came in an easy carry bag but would like it to be easier to open retaining the built in handles of the bag. It was priced nicely in this current market.

HTH pool shock

Worst product ever. Wouldn't dissolve and our pool kept getting yellow with dark spots on the bottom of the pool. Took our filter apart and it had clogged the filter there was so much in there it took about an hour to rinse the filters off. Will never buy this again.

My favorite for my pool

[This review was collected as part of a promotion.] Love HTH brand, it's my favorite, as it works great. I have a big above ground pool and use the Super Shock Treatment to help clear the water and if any green algae starts building up. Put the treatment in the pool and within hours is crystal clear. Only thing is, be careful when opening it up, sometimes if the powder comes out, like say in a breeze or in the house, you can taste it.

Works great in our small pool

[This review was collected as part of a promotion.] This product was very easy to use, and worked quite well for our 14 ft backward pool. It did not leave a strong smell and definitely helped cut through some green that had sprung up between treatments.

WORKS FAST

[This review was collected as part of a promotion.] I was so impressed with the effectiveness of these pool products, they are fantastic and work great and ohh so fast, This is great shock because it doesn't have any cyanotic acid and that's a plus for me.

Great product!

[This review was collected as part of a promotion.] These are definitely great quality pool chemicals! I usually buy the regular shock but I am very impressed with the super shock and I will definitely be buying it again. Helps to keep my pool balanced and beautiful all season long. Great quality products for affordable prices. Definitely the only brand I use when it comes to my pool. Product works great and I would definitely recommend it!

works well!

[This review was collected as part of a promotion.] this has turned our pool from a pond into a crystal clear oasis! perfect and ready for summer. its hard to keep our pool clean during the cold winters, but this worked in no time when it was pool season.

Green be gone!

[This review was collected as part of a promotion.] This Super Shock treatment does exactly what it says it'll do. It literally zaps the nasty green outta the pool. It doesn't over do it though... the ph is still great after treatment. Works better than best and I was amazed at the clearness of my pool.

Awesome product

[This review was collected as part of a promotion.] This product is amazing! Love that there are no harsh chemical smells. Easy to use and doesn’t require much product to effectively do the job! No residue left behind and no slick feeling left of the bottom of the pool!

Great product!

[This review was collected as part of a promotion.] One of this biggest problems I see with our pool in Arizona is the algae build up. Summers here are extremely hot and algae loves to hang out. This product has helps immensely to avoid the nasty build up and clear up the waters. Works fast as well. Great product. Will buy again. I received this product free of charge for my honest review.

Great product

[This review was collected as part of a promotion.] So I’ve learned that with having a pool, you’re always going to have issues with something. Little did I know that there was a great product that I could put in there and clear everything up fairly quickly! This has been a lifesaver.

Works great!

[This review was collected as part of a promotion.] Received the shock treatment and used right away. Within hours the pool was so much better (no more green swamp) sparkling with correct levels. Would recommend for sure to any pool owner. Also very easy

Powerful but gentle

[This review was collected as part of a promotion.] I love this product. It is powerful and keeps your water crystal-clear and beautiful. But it is also gentle in that it won't fade your liner and helps cut down on that chlorine smell and eye irritation. Just add it to the skimmer with the pump on and enjoy beautiful, clear water all summer long.

Blue water!!

[This review was collected as part of a promotion.] This stuff is awesome..My pool was green for a while I added hth super shock treatment along with the hth blue sparkle tab and now my water is bright blue again..This stuff is great I will definitely be using this for my pool this summer..

May require experimenting, but it works wonders!

[This review was collected as part of a promotion.] I had a very dirty and neglected pool to deal with at my rental property, and this turned out to be quite an effective and efficient problem solver. My experience with this required me to use a little more than what it originally suggests to get the water clear enough due to the already terrible conditions of the pool (it was completely black!). But after a while, the water came out crystal clear. Highly recommended this for very tough jobs!

Very effective!

[This review was collected as part of a promotion.] I've been using hth chemicals to treat my pool for years. This shock treatment works quickly & effectively at killing any odors & algae growth & clears up my pool water. It works fast, easy to use, does a great job

Let's swim!!

[This review was collected as part of a promotion.] Tried this on my pool that was green. And I didn't want to mess with it. But I put a bag in and let me tell you.... The next day it was almost clear, I did add a little more since it was bad. But it worked and was too easy! Love that it gets rid of algae and bacteria and helps keep my pool clean. So worth it!

Works Quickly and Efficiently!!!

[This review was collected as part of a promotion.] One thing I’ve learned after having a pool for a few years is that shock is the absolute most important thing you can give the water! My pool hadn’t had anything in it all winter and I didn’t use anything when I opened it this year. So using this shock was it’s first dose of pool meds besides the chlorine tablet. So I only used one bag (which is unusual because I normally need two at first). It cleared up the clouds and green and made it a beau...

Wonderful

[This review was collected as part of a promotion.] We love it we actually use it for Both pool and cleaning its very good product and it help cleans the pool.... Defienely would buy for duribg summer time we plan on purchasing more for summer and cleaning

Worked like a charm!

[This review was collected as part of a promotion.] We have an above ground pool that has to be pumped out and refilled each year. We always have a little green left to fight, once the pool is refilled. We were having a hard time getting rid of the green, until we tried this. No more green. This stuff is good!!
