HTH52028 Ultimate Shock Treatment Swimming Pool Chlorine Cleaner, 1 lb (Pack of 6)

Works great, I use 1/2 a bag every week and it helps keep my pool crystal clear in this FL heat. Highly recommended.

After 2 weeks of fighting algae, using Leslie's pool shock, and constantly trying to figure out how to at least see the bottom. This just made the water perfect. $35 for 6 lbs too. Now, I'm not embarrassed of the gross look and able to use it again, I can use the recommended amount weekly and while not having to spend a fortune and time.Edit: seeing a lot of negative reviews. You absolutely have to balance your alkalinity and PH first before adding any pool shock for any brand. This is my first full season owning a pool and my green water was gone over night after giving time for the baking soda to mix in for a few hours and then shocked the pool overnight. Also, don't pour the shock in directly. Mix it with warm water in a bucket and pour it around the pool that way. I'm confident I won't have green water again with this very simple weekly maintenance

It makes the water sooo soft it feels like silk gliding across your skin. Aahh....It cleared up the green tinge in my pool water in less than 30 minutes. AMAZING!! The only thing is it's quite expensive, $65 for a 6pk compared to $69 for a 12pk of my regular shock treatment so I will only use this occasionally to prevent the green tinge and when people are coming over to swim. I'll use my regular shock the rest of the time.

The product is good, but the price is much higher than I usually pay. The description did not include number of bags, just that the box contained one pound bags. Only six bags were in the box and I expected 12 for the price. I pay $39 for six bags and Amazon charged $61 for six of the exact same bags . That's just mean!

Repurchased these as it does a good job on cloudy pool water. Perhaps overpriced (?)

So the features sheerness and warmth are not really applicable but I put 5 stars there anyway because it is a great product. This is my go-to pool shock and they were out locally. Was so happy to find this on Amazon. Was a bit disappointed in my mail carrier for delaying delivery for some unknown reason but I finally received it.

We live this all-in-one formula which has been hard to find locally. Getting a bill package delivered and at a fair price made opening the pool and getting in with the family a breeze.

I tried a cheap Walmart brand shock and it literally bleached a couple bottom sections of my liner so I stick with name brand only. This keeps the pool clean and no more bleaching.
