Edit: Just came back to look at my "previous purchases" and wow the price dropped by a third to $4! From $12 to $4? Wth??? I'm gonna bump this up a star (still easier on the pocket to buy in bulk 4 x 24 = $96) for now, but I did notice that this stuff is a lot more effective than others. Works great! Cleared up algae in 24 hours and my pool is sparkling. Knocked a star for the price. After purchasing this, I came across "related items" and a 24 pack is around $55-$65. This product is $12 (currently) so $12x24 pieces = $288. If you need just one pack, this works but saving money in the long run I'd go bulk

Added each week and it keeps my pool sparkling clean. Only place to find the 7-in-1. Don't bother with the lesser ones. 7-in-1 is the only way to go. It covers all aspects of water treatment

Super shock is the best! Don’t use it for the pool, just use a teaspoon to keep the front loading washer clean since the seals can get nasty.

This stuff works!! It's concentration is good enough that you only need two packs for a 24000 gallon pool. It's price is pretty good, and I have to say for someone who just started cleaning his own pool, this is a lifesaver. It's like a reset button for those who are beginners and need help with pool maintenance that's gets out of hand. I have poured it into my pool both ways (one Just dumping the powder, and one mixing it in water and then pouring it in). It makes no difference, and I think it easier to just pour the content straight in. It didn't discolor my pool.qq

I use this to shock my pool and with it being 4 in 1 I don't have to add other chemicals! This makes maintaining my pool so much easier. Great product! Highly recommend! A++++++

Product worked as described. Went into solution easy during premix with water.

Have went thru 32 backs of shock on a 48,000 gallon pool that hasn't been touched in 3 years... I now have have clear blue water, going to FLOC it and see if that will finish it up.

We switch to this from In-The Swim and Leslie's brand Shock which clouded up the pool for a couple of days. This BY FAR does a better job, The pool hasn't been cloudy since we switch.

Our pool was turning clear in the filter stream with this product. Granted we also had just cleared out a bunch of leaves and turned the filter on. But past products took forever make the pool clear (after winter).

I ordered HTH Pool Shock because they had the best prices at the time. I've been using HTH in my pool for several months now, once a week, and I get the results I expect. I've tried several different vendors over the years and HTH is as good as any. No complaints
