Great for our swim spa

[This review was collected as part of a promotion.] We have one of those infinity swim spas and we're pretty new to pool ownership. This shock seems to work as well as any other we've tried, and our spa is clean and comfortable to go in. We shock once every two weeks or so.

[This review was collected as part of a promotion.] I received HTH Pool Care Shock Advanced a few weeks ago. I used it to shock my pool since it was feeling kind of slimy on the bottom. Within hours it started to work. Quite impressed, By the next day the pool looked great. No slimy and not a bit of green in the pool. Great brand and won't us anything else anymore.

Shockingly clean

Would Recommend

[This review was collected as part of a promotion.] Anyone with a pool knows that water balance is important. It can also be difficult to maintain if you're a DIY-er like myself. Fortunately, this pool shock is a fantastic help. There's easy to use instructions right on the bag, so anyone can figure out how to use it. It works well and doesn't throw off my water balance.

Works ok

[This review was collected as part of a promotion.] I feel like every time I use the HTH brand, I have to use more of the chemicals than any other brand. Brand. Using the pool shock, I had to use an extra packet to get the same results as I would if I used a different shock. Chemical-wise, it's exactly the same as any other shock, but for some reason it does not yield the same result. I often use test strips to test my levels and I have an above ground pool.

Works very well

Would Recommend

[This review was collected as part of a promotion.] This product works like magic. Instructions are very clear and easy to follow. I was able to clear all the algae from my small above ground pool. It took 2 days but in my opinion still better than draining and refilling. Be sure to test water and make adjustments before swimming. This brand has test kits and pretty much everything you need.

Amazing Pool Products!

Would Recommend

[This review was collected as part of a promotion.] I have recently used a series of HTH Pool Care products. I have used the Shock, the Advanced Shock, the Algae Guard 10, the pH Down and the Phosphate Remover. My family and I spent a big part of the summer at camp, and allowed our 30ft round above ground pool to turn a very green, swampy, algae filled pool.
