Ratings & Reviews for HTH 115.2-oz Pool Shock

Green to blue

This product didn’t work , the yellow powder is till showing in pool. We tried vacuuming numerous times and it sucks it right back into the pool. I tried adding other shock and once stirred my pool is still green.

Must Vacuum to Waste, Chlorine Turns Water Green

I only gave 2 stars because now I have the problem of my water turning green for 24 hours every time I add chlorine. It’s always blue again the next day but shows 0 chlorine. I’ve had this pool for 21 years and never had chlorine turn the water green until I used this product. I have no idea how to fix this problem. I bought and used this a month ago but neglected to read all the instructions beforehand. I have a cartridge filter without the ability to vacuum to waste which is extremely impo...

sparkling clean pool

[This review was collected as part of a promotion.] So, I've been waiting to use this product for when I felt I couldn't do anything else to fix my pool. We have had so much rain lately and we have too many trees. So my pool was a hot mess to say the least. I wanted to be able to use it for Labor Day, at least one more weekend before closing it. We used the HTH Super Green to Blue and let me just say I'm sold!! I was so impressed with how well it cleaned my pool and how fast. This is going to be...

Great treatment

[This review was collected as part of a promotion.] I was happily surprised with how quickly this product worked. Our pool has never been as crystal clear and blue as it was after using this treatment. I highly recommend using this product and especially this brand.

Great pool chemicals

[This review was collected as part of a promotion.] These are great pool chemicals. It has absolutely helped us keep our pool blue and not green! We use these once a week and have been very pleased. It's a great product to use if you are maintaining your pool yourself.

Works great

[This review was collected as part of a promotion.] I’ve been battening with a green algae pool and when I started green to blue it really showed results within 24 hours!!! This product is now our go to products!!! It's easy to use, instructions are clear, and results are.amazing

Handy packets

[This review was collected as part of a promotion.] I really like the handy packaging that this company packages the shock in. It's very handy for those of us who want to do the job quickly without fussing over measurements and conversions. I always know how much I need for the job and never over treat my pool.

Worked like it should, nice blue pool

[This review was collected as part of a promotion.] This stuff works! We have had a hotter and hotter summer which plays havoc on our pool. This stuff really works and is easy enough! I really am impressed on how quickly it works too. Will get more of this for next year

Worked great!

[This review was collected as part of a promotion.] We were at the point with our pool where we thought we were just going to have to dump it and start all over before we tried it. Our pool was so green that we didn't think anything would work to get the water clear again again. We added the HTC Green to Blue to our pool and after letting it sit for a day the water was back to normal. We did have to adjust the amount added due to the size of our pool being much smaller than what each packet is s...

Tried to use the shock treatment in my pool

[This review was collected as part of a promotion.] I used shock it to take the green out of my pool, it did not work well My pool still stayed green and did not turn light blue. My husband after several days had to use the chemicals he usually uses. I have a very large pool maybe there was not enough product .I hope this product was not for a small spa It was easy to pour out of packets to use. Maybe this product will be tested and be more stronger in the future. I was disappointed it did not w...

Great

[This review was collected as part of a promotion.] I was starting to notice that my pool was starting to look a little green. I used this product and noticed the difference in a little under an hour. I came back and checked 2 hours later and the pool looked 100% better!

Left our pool crystal clear!

[This review was collected as part of a promotion.] I live in the South Eastern U.S. where it stays scorching hot all summer long. I've always had problems keeping our pool clear and pretty for most of the season. Between the heat and the storms, I'd all but given up. Enter in this AMAZING product! It's left our pool water crystal clear and is easy to use/dispense. I highly recommend!

Great product

[This review was collected as part of a promotion.] I bought this product to try and save the water in my Pool because its big and i dont wanted to change it so i tried the shock treatment and it worked great, saved my water and it came crystal clear and I’m happy

Great results! Easy to use packets

[This review was collected as part of a promotion.] Super Green to Blue shock system works great! These prepackaged pouches makes it much more convieniet to clean pool. My pool was starting to get slime and alge and it was very frustrating as I had just filled my pool up from the same issue and within a couple days it was starting to do the same. I used this product step by step and this product fixed my issue. I was able to clean out debris with pool vacuum and the smell of water smelled clean ...

NEVER use this garbage product...HORRIBLE.

NEVER use HTH green to blue...makes everything twice as much work and your water very very cloudy...one big mess.

Make it blue!

[This review was collected as part of a promotion.] We live in a hot, humid climate which we appreciate so much. Because of this climate extra work is required to keep our pool healthy. A few years ago we let a few pool companies try to take care of our pool. After countless tries with different companies to service it, we decided to do it ourselves. We like it blue and clean! This product works fantastic! Makes it easier to sweep and vacuum..thank you! Treats up to 20,000 gallons, fine for ...

It works!

[This review was collected as part of a promotion.] I have been using this for the last couple of summers and it does it’s job very well. I usually pour it at night and next morning it has cleared my pool all is left is to vacuum the bottom of the pool.

It works

[This review was collected as part of a promotion.] I used this product to turn my green looking water back blue. I thought at first this product was not going to work after following the directions on the box. I ended up pouring the entire box into the pool. I left the filter running and within 24 hrs, my water was slowing turning back blue. If your water is a dark swampy green color, I would advise you to just empty and refill but if its just green tinted like mine, if should work fine.

Sparkling Results!

[This review was collected as part of a promotion.] My family has been bugging me to get the pool ready since March/April. I saw HTH's Green to Blue and figured I would give it a try for the first time. The algae bloom seemed pretty thick and still, I only has to use this two part shock treatment twice! Past experiences have not always been this simple during the winter to summer transition. Easy to follow instructions were not only inside the packaging, but also online and in video format! This...
