HTH Pool Care Shock Advanced — Granules, 6 Pack (6 lb total) — Pool Shock Treatment for Weekly Pool Sanitizing

I've used this shock treatment several times and it works exactly as expected. It's easy to apply, dissolves well, and helps keep the pool water clear and clean. The individual packets make it convenient to use the right amount without any guesswork. Great product that gets the job done every time.

Compared to other quick dissolving shock for pools, this is a very good price for a 12 pack. Works with salt water pools. And with Walmart plus delivery in as quick as next day if needed. Yes you can get the same chemicals from Home Depot Lowe's and Amazon but Walmart has been very reliable.

It does take longer to dissolve but works well. Due to the rain lately we've had to deal with algae compared to last year. I'm assuming it's due to the rain but I'm having to use 2 bags every 2-4 days. It seems I remember last year only having to shock the pool 1 x a week and only 1 bag. Unless this product has been changed. I will continue the rest of this summer and see how it goes. I may seek a different product next year as 2 bags 2-4 days seem excessive.

I bought this HTH brand after seeing great reviews on multiple pool care sites. Walmart online purchase and pick up was by far the best price. I was very pleased with this shock. Does really well for us. Crystal clear pool. I followed the directions and mixed in a bucket to add it as a dilution solution. I preferred to add over time into the return stream over 5-7 minutes. If done slowly it disappears almost immediately. Works on my 24 round above ground.

Walmart's pool supplies are consistently less expensive than other sources and HTH Pool Care Shock Advanced is a perfect example. I've used HTH products for years and have never had any issues. The Pool Care Shock is something I use all the time. I live in FL and between heavy summer rain and the heat and sun, it doesn't take much to throw your pool chemicals out of whack. I use HTH shock (and other HTH products) to keep my pool crystal clear and safe!

we like these HTH brand for chemicals and they work best for us. we use the shock, stabilizer, and3-in pool tablets by HTH. the pH has to be right before you can add the shock or you will waste a lot of shock. at the beginning of each year we also stabilize our pool as soon the chemicals arevin the right range which is necessary. I personally desolve the shock in pool water by stirring it with a plastic paint stirring tool. I put a little and a bucket at a time and throw the water toward the center of the pool and some around the edges. it works well for us that way and we don't have a lot of residue everywhere. be sure to use your pool water and not faucet water so it has the same chemical levels as your pool water. that's just my theory. we vacuum next day.

I've switched to HTH Cal-Hypo for my weekly pool maintenance, and it's been excellent. It dissolves quickly, keeps my water crystal clear, and I like that it doesn't add cyanuric acid, so I don't have to worry about chlorine lock over time. Great value, especially when it's on sale. I'll keep buying.

The price kills me. It's chlorine. How can they charge this much for chlorine or any type cleaner for that matter. This is ridiculous we should be taxing billionaires 90% especially these corporations.

Harder to dissolve, leaves more remnants that other brands. I have a small filter system so I can't add directly to water in the pool, it will make stain spots and possible holes. So I dissolve it best I can and add to the skimmer. Now if you have a large sand filter, I would think it would work ok.

This product arrived two weeks late. When it did arrive, it was a weak and inaccurate product. On the packaging it says that it is 1 pound, but as you can see by this photo, it only weighs 10 ounces. The product is also very poor quality. I have put three bags in my pool and there has been no change.
