Would Recommend[This review was collected as part of a promotion.] HTH Pool Care Shock is the easiest and most convenient way to treat the water in my pool. I use it after heavy swimming loads to keep my pool sanitized and the water crystal clear. It is the best product I have tried and it quickly goes to work without causing chlorine lock or over stabilization in my pool water. I use it every week to keep many common pool water problems from occurring. It really is an affordable way to care for my pool.

Amazing
Would Recommend[This review was collected as part of a promotion.] With this shock treatment not having chlorine in it I was a little skeptical, but to my surprise it worked amazingly well and fast. My pool had started getting cloudy and had a little green to it. I poured two bags in it and over night my pool was sparkling clear.

Always use
Would Recommend[This review was collected as part of a promotion.] Here is one name brand that I have the utmost confidence in. It always works as it should. I am never concerned if what I am doing is going to work when using HTH. At the beginning of the year I always shock the pool with this. I use 3-4 1lb packages and just that quickly the levels are under control. It’s that easy.

Fantastic!
Would Recommend[This review was collected as part of a promotion.] HTH Shock is my go-to for my pool shock. I have a 24 ft round above ground pool, and keeping it sparkling is essential. The Shock helps out much more than regular shock. It is great for weekly treatment and also after much heavy rain. I put the amount that my pool requires into the skimmer and within several hours, my pool is fantastic looking. My pool is surrounded by trees, so there is quite a bit that gets into my pool (and hello algae!...

Works Great!
Would Recommend[This review was collected as part of a promotion.] I love HTH products. They have never failed me it my pool. I recently tried the new HTH® Shock! Treatment and it too was amazing. I was out of town for a bit and when I came home my pool had a grimy haze to it. I simply poured the HTH® Shock! Treatment around the edges of the pool and a few hours later the water was crystal clear. It’s truly that easy. It dissolved super quick and you could see it working right as it hit the water.

Works well
Would Recommend[This review was collected as part of a promotion.] I used two of these after the storms came thorugh. The HTH® Shock! Treatment works as expected It helped clear my pool very well. Having the shock in pre mesurued packets saves time, you can just cut the packet open and dump it in.

Great for above ground pools
Would Recommend[This review was collected as part of a promotion.] We love this HTH Shock! Having an above ground pool with a liner out in the country, you cannot relax on chlorinating, cleaning and shocking. You will have a big mess on your hands really fast. HTH Schock! makes the pool clean and clear. The best part is that you don't have to wait days to get in after shocking the pool with HTH. It is too hot for all that. We swim every day. Great shock, highly recommend.

Works so so..
Would Recommend[This review was collected as part of a promotion.] We recieved the Shock free in exchange for a review. We were very excited at first because we had just run out and many pool supplies are ridiculously pricey now due to price gauging.. it seemed to help for a short while but the past few weeks our pool has started turning green entirely too often despite using the shock treatment. Might work better in a smaller pool, I however am not too sold on it for our pool.
