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

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.

Works good

[This review was collected as part of a promotion.] HTH Pool Care Shock Advanced has been working great; especially, after a hard rain. Just put it in to our skimmer and after a few hours, our pool is looking great. It really helps considering we have some trees near by.

Quick and easy

[This review was collected as part of a promotion.] This HTH 1 pound Pool shock really did it's job at shocking my pool water by being the right amount of shock for my pool size. I and the family really appreciate how I could shock in the afternoon, and be able to swim again in the early afternoon. I really love how crystal clear and clean my pool water is after using this HTH pool shock.

HTH quality pool products

[This review was collected as part of a promotion.] HTH is a great manufacturer of pool products. I would recommed their products to others to assist in the summer care of their pool. Shocking is something that should be done often especially with little ones using the pool as you never know what they are leaving behind.

Great for your pools

[This review was collected as part of a promotion.] I have trusted HTH Pool Care products for years. This Care shock Advanced is another great product. If you have a pool and are not using this product you are missing out. I highly recommend this product to all pool owners.

Perfect for weekly use

[This review was collected as part of a promotion.] The Advanced Shock Treatment is perfect for weekly use. With the high temperature shocking weekly is a must here in Arizona. The 1lb bag are just the right amount to help keep chemicals balanced and keep the water crystal clear.

HTH is the brand I trust

[This review was collected as part of a promotion.] This HTH Pool care shock advanced helped to make the pool super clear and sparkly. The water looked amazing after use. Crystal clear like you'd see in the tropics. I love this brand and trust them to keep my pool looking and feeling good.

Love it

[This review was collected as part of a promotion.] The shock works well and is much more affordable currently than what I usually get from my local store. It dissolves well but I do lightly brush the pool bottom where any solid particles make it to the bottom about 10 minutes after application.

Amazing Pool Products!

[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. Upon using the above mentioned products, our pool is now crystal clear. I will say, make sure you read the directions fully and carefully. ...

Great shock

[This review was collected as part of a promotion.] HTH® Pool Care Shock Advanced, 6x1lb is the absolute best shock I have used to keep my pool clear and clean. This shock is easy to add and always balances nicely to what I need. Very impressive for the price.

Works fast and effectively :)

[This review was collected as part of a promotion.] After weeks of dreary gloomy rainy weather my pool turned 50 shades of green- ugh. Not shocking weekly as recommended, not even keeping chlorine tabs in the floater because I just didn't care since we weren't able to swim anyway, big summer bummer set in. Finally the sun appeared and everyone wants to dip their toes again so in went the HTH Shock Advanced (following the instructions on the package) with fingers crossed and swimsuits ready. Our ...

Great product!

[This review was collected as part of a promotion.] This product is amazing. We try to keep our pool looking so clean but after the rain it becomes cloudy and yuck looking. With one of these shock treatments everything looks great again. I highly recommend this to keep your pool looking so clean.

Works great!

[This review was collected as part of a promotion.] This pool shock worked great in our pool! We had used this when our pool got rained in for several days. It started turning green and I had used just one pack of this plus ran my filter overnight. It cleared up my pool perfectly and we were able to use it the next day! Definitely recommended!

Keeps the Pool Crystal Clear!

[This review was collected as part of a promotion.] The HTH Shock Advanced 1lb packs are a great shock to keep your pool clear and ready for use all year. One package of shock spread around the pool once a week is all it takes. The granules dissolve as desired without leaving any sitting on the bottom of the pool if it is evenly spread. One package should cover approximately 13,000 gallons. However, one per week keeps my 18,000 gallon pool along with tablets keeps it clear with minimal effor...
