Ultimate Shock Treatment

I read 12 pack and only received 1 loose packet!

This stuff clears up my 18 ft above ground every time. Very effective, at a good price.

The is my go to shock when I can’t seem to get my pool crystal clear before parties or bbq. I can put it in the day before we have company and wake up to it super clear and clean in the morning. 10/10 recommend for a fast acting job. Just keep in mind it doesn’t resolve you keeping up pool maintenance.

Trash. Turned my water brown instantly and of course it was being set yp for my daughter's surprise birthday party. We have well water. So we emptied it and tried it again and yet again brown instantly as soon as I added it. So we bought a $500 whole house Filtration System with 4 filters one including rust as we thought maybe it was that and we cleaned it all out let the water cycle through a few days and tried it yet again and sure enough it instantly turned the water nasty brown. So I again empty the pool wiped it all out as it even left a brown residue and it did so every time so now the bottom of the new pool is stained. So I finally just filled the pool with just the well water to see what would happen and it is crystal clear and it's been 2 days and is still crystal clear. I'm not sure what it is in this product but it turns well water a nasty nasty brown instantly and leaves a brown slimy residue on the bottom. This product is trash. I tried to return what was left as it is a smaller pool and eventhough it is within the return period it says I cannot return the item. It deserves 0 stars on all accounts. Very disappointing especially being it was initially a birthday gift and it a as like giving her a swamp. Not pleased at all! Unfortunately I should have thought to actually take a good picture of it but I was so irritated just trying to get it so she could enjoy it that taking pictures of it wasn't on my mind and I'm not going to ruin the crystal clear water by adding more of this crap. That pic was the first attempt the second was worse.

I thought it was a pack based on the price. I should have read it better. I paid $19.99 when I bought it. 7-17-23. Waaaayyyyy overpriced. They sell the same product even here on amazon for about $8 and are about $8 every where else. Don't buy from this seller.

This is a great product and works very well but I was really disappointed when I went to Walmart and found these for $3.50 apiece when I paid $15.99 apiece here on Amazon. So just a heads up for all of you out there, Walmart has these a lot cheaper.
