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

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.

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.

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 been using HTH Shock advanced treatment for about 2 years. It's extremely effective. Keeps our pool clean and algae free. I use the HTH 4step pool care program and it's been great. The quality and performance are really good. I've had fantastic results since starting with the HTH. Also the price of this particular product is fantastic! Their chlorine tablets are also great. (The price is amazing too) Highly recommend will continue to use in the routine maintenance of our pool.

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!

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.

I give this one star, but it deserves 0. I have had a pool for well over 30 years, and this is the crappiest shock I have ever used. My pool is less than 6000 gallons and this says for twice that. It does not clear it only makes more to vacuum off bottom. Made the mistake of trying to save a little and bought a case of this . Do not buy, not worth your time and expense.
