Ratings & Reviews for HTH 12 -Pack 16-oz Cal Hypo Pool Shock

Essential

[This review was collected as part of a promotion.] Everyone who has ever had a pool knows how’s important shock is when opening your pool and for monthly maintenance durring the peak heat. This product helped keep my pool crystal clean and enjoyable for the summer.

Good price… Questionable quality

Purchased one 12 pack, and after opening, it noticed that the individual packs appeared to have been stored in properly. The ink was all smeared on those packs, which indicates they were stored under very wet conditions, causing condensation. I returned that pack and noticed that they had more available. So I asked it associate to open one of them. This pack in the other one both had similar sticky inner packaging and a little bit of runny ink. But the product still felt like it was granular, so...

Check packets inside larger package before leaving

Individual packets were moist and the ink was all smeared. Not sure if the product is OK. Will return.

Works as advertised

This product is a great value in the 12ct pack

Great product

[This review was collected as part of a promotion.] I bought this hth pool care shock advanced about a month ago for my pool. I love it this stuff works well clears uo my pool every time. I love the hth brand I've never had a problem with it at all always works as it should

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.

HTH Pool Shock really works well.

It depends upon the amount of algae in the pool. After the hurricane, I used 4 lbs. one week. The next week I added 2 lbs. and another 2 lbs. later that week. The algae was basically gone and the water was clear. I'll have to add a pound of shock at least once a week to prevent any algae build-up and keep the water clear.

Best

[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.

So Effective!!

[This review was collected as part of a promotion.] This pool shock is a must have for every pool shed. When my pool starts to look a little funky or even just before or after having people over I love to throw some of this in and give it a little extra TLC.

great for pools

[This review was collected as part of a promotion.] these pool chemicals were great for my pool right before closing I added these to get her all cleaned up and shiny so she can have a long winters nap and be fresh and ready when we open her again in the spring!

Awesome for the pool

[This review was collected as part of a promotion.] I received HTH pool care shock to try for my pool. I love that this brand of shock comes in convenient bags to use. The bags are not overly heavy and are easy to carry to my pool. I had no problems opening the bag and dispensing the shock into the pool. It worked well to clear up my pool and I am very satisfied

Shockingly clean

[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. I have a 24-ft pool which normally ta...

Works very well

[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.

Cleans exactly as should

[This review was collected as part of a promotion.] Great product over all only concern/problem is the granules Are large and have to be stirred around do to not de solving completely also leaves a slight film on top of water but does make water crystal clear

Great System For Clear Water

[This review was collected as part of a promotion.] I have been using the HTH products for a while now and they have kept my pool clear and clean for the past 3 summers. The shock works great especially after all this rain we have been getting here in Florida. It clears up any algae in no time without a lot of scrubbing.
