HTH Pool Care Chlorine Shock Granules for Algae Prevention, Fast-Acting, 12 pack

The best shock/pool chemical brand. I won't use any other in my pool. It's not aggravating to our skin and clears up any algae as long as i double or triple shock pool. Worth every penny.

If you own a pool , this is nothing new to you. We're always looking for the best price and free delivery as this cal-hypo is something we use regularly. Walmart consistently has good pricing and availability. HTH is a good company with reliable, consistent products! 😀👍

Great price! Great product! I have used HTH products in the past and have received the same or better results than more expensive products that perform the same functions. Combined with Walmart's pricing this purchase was a no-brainer!

As a pool owner, I am very familiar with HTH products. I find them to be of great quality at a good price.

This pool shock is consistently available at Walmart and is high quality but cheaper than leading brands. My pool Stays in great shape.

I use it along with the liquid, this is also an excellent product, I pour 1 bag before the liquid chlorine, that all it needs, fast and easy.

Delivered to wrong house below is a picture of my front door

What I'm reviewing here, is the seller, not the product. I couldn't even take the bags apart from how stuck they were.

This was delivered to my front porch at 12:30am this morning. We awoke to our dogs barking and two people standing outside our bedroom window holding their phone up taking pictures. Then they sat in our driveway for several minutes. Very alarming. We did not know they were delivering a package until after they finally drove away. We went outside to see if they had stolen anything or messed with anything on our property and saw the package. If I had been home alone, I would have called law enforcement when I saw them outside my window. This was not delivered at 6:06am as the text reports.

This made my pool worse! I always use HTH products without issue, even with algae bloom. But this time was very different. Not sure how this is for algae, bought 12 bags and maybe 2 days in the entire time frame where algae was almost gone. Went through entire box and it did nothing, some days even turned dark green after adding it. Went back to my other HTH shock and worked Instantly. This is what I get for not just sticking to what always worked I guess.
