Easy effective shock

Good effective shock product. Dissolves quickly and raises the chlorine level. I have no idea what the 4 in one refers to as there are no details to explain it on the package. I also noticed that the packages are apparently not completely sealed as i could smell the chemical odor in the closet where the unopened product was stored.

Quick and easy shock product

I used one of the 1 lb. bags of Shock Clear to increase the chlorine level in my pool. After waiting awhile for my system to cycle a few times, I retested my water and the chlorine level as perfect! It was also very clear. No chlorine smell and dissolved very quickly.

Clears up quick!

We have had an abundance of rain this year. That always makes maintaining a pool in the spring a challenge. We have been able to keep our pool sparkling with this product and when we had one cloudy experience after two days of stormy weather, we were able to clear it faster than normal. Our pool has been swim ready consistently and it’s been a beautiful sight!

Clorix Pool and Spa Shock Clear

My name is Pat. I am 72 years old and live in Fort Pierce, Fl. I have been maintaining my concrete/gunite pool for 23 years ever since I moved to Florida. I have been using Clorox products most of that time. I use the Clorox Shock Clear on a weekly basis and if we have had heavy rain, I’ll use an extra bag. It keeps my pool sparkling clean and kills any algae or bacteria that may be in the pool. I can swim after only 15 minutes of putting in the shock which is very convenient. I love the simplicity of this product. Just one 16 oz. bag a week, which dissolves very quickly, wait 15 minutes, and I’m good to go. I have recommended this product to friends, and they find it to be a great product also. I highly recommend this product for anyone looking for an easy way to keep their pool sparkling clean and bacteria and algae free

Top of the line granule shock

Clorox pool shock packets are a game-changer for pool maintenance. Their compact size makes them super easy to store, taking up less space for other chemicals, When it comes to action, they work like a charm, quickly dissolving and getting to work faster than you’d expect. They pack a punch, too, seeming to outperform other brands I’ve tried in terms of power. Definitely a top pick for keeping the pool crystal clear!

Clorox Shock Clear effective and quick dissolving

I started using Clorox Shock Clear as soon as the summertime weather hit. I’ve been adding it to my pool every 7 – 10 days to maintain water clarity and cleanliness. I have a 15 year-old 10,000 gallon pool with an attached spa. One of the standout features of Clorox Shock Clear is how quickly it dissolves. After adding it to the pool, we can swim within the stated 15 minutes, but generally I wait for at least 30. It makes the maintenance process swift and hassle-free, allowing us to enjoy the pool with minimal downtime. While Clorox Shock Clear is effective, I noticed that for a little more money, you can opt for the Clorox 6 in 1 formula (Shock XTRABlue). The Clorox Shock Clear is a 4 in 1 formula. The XTRABlue version offers additional benefits and functionalities, making it a more comprehensive solution for pool care. I would still recommend Clorox Shock Clear for those looking for a reliable and quick-dissolving pool shock solution. However, if the price difference between Clorox Shock Clear and the 6 in 1 formula (Shock XTRABlue) is minimal, I’d suggest going with the XTRABlue for its added benefits (whatever they are).

Clorox Pool System is My Go-To

I use exclusively Clorox pool chemicals and enhancements for many reasons: – They’re easily accessible and are sold at most major retailers. – They’re a good price value in comparison to other well-known pool products. – I feel more confident in treating my pool successfully with using the entire Clorox system, as it’s simple and easy to understand. Recently I used the pool shock for weekly pool maintenance and, as always, I am satisfied with the simplicity of use and the quality of the results in getting my pool sparkling clean and pure.

Quickest dissolving shock I’ve used

Clorox Shock Clear 4 in 1 Formula one pound bags were about the easiest dissolving chlorine shock I have ever used in my vinyl inground pool. They poured out of the bag with zero clumps to splash and raised my chlorine as expected for an available chlorine of 40%. I have to question though why isn’t there any mention of the other 3 chemicals in the formula. The warning “DO NOT mix with other chemicals (a violent reaction may result) doesn’t make the product seem safe without knowing what the other 57% makeup is. I think the Swim-ready in 15 minutes notice is a bit dangerous too, as with all pool chemicals you need to read the whole statement on the front and back to understand some of the claims.

Another Great Product from Clorox

We love Clorox Pool & Spa Clear (32706CLX) and definitely recommend it to everyone who wants a fantastic shock product. The product is easy to use and I love that this one product kills both bacteria and algae. To apply, just spread it over the deepest end of the pool and watch it dissolve quickly. You don’t have to worry about any possible damage to your vinyl liner. I also love the convenience of the packets being already measured out for me. No guess work involved. Another benefit is there is not a long wait before you can get in the pool. Within 15 minutes, the water is safe. This product makes the water in our pool look clean, fresh, and very inviting.

I have a 18X36 in ground liner pool. We had a new liner installed in October of last year. Installed about 17 bags of Clorox pool salt after the install for the salt chlorinator. Discovered we had a leak and was losing water. Pool just kinda sit over the winter till it warmed up to find the leak. Got the leaked repaired and got pump back up and running. Again add Clorox salt back. Pool was green and cloudy, used the Clorox shock along with Clorox ph up product to get the ph up. I have just started to do my own water testing and do my own maintenance. Pool looks great now, it’s crystal clear. We had a a lot of people over this weekend and I just did a backwash and added some Clorox 4 in 1 shock.

Clorox Pool Shock: A True Life Saver!

Review of Clorox Pool Shock: A True Life Saver! I recently faced a pool owner’s worst nightmare: my pool turned green and was full of algae. In a state of desperation, I bought Clorox Pool Shock and started using it right away. I shocked the pool twice a day for three days, and by the fourth day, the transformation was unbelievable—the pool was clear and blue again! This product is literally a life saver. The need to drain the pool was completely avoided, saving both time and water.

Best chemicals for your pool

I have been using this product for 4 years now and never had an issue. My pool is always balanced and clean. I use all clorox family like chlorine tabs, ph, algae, clarifier and of course the clorox Shock. Great products.

Best Shock!

I have used many different shocks over the years. I keep coming back to Clorox shock because it works better than all the rest. It is affordable and easily found in most stores. I like the packets coming in 1 lb bags for easy measurement. Works the best!

Worked really well!!

I was chosen to try the Clorox Pool and Spa Shock Treatment. This is based upon my opinion only. It’s a 4 n 1 formula, kills bacteria and algae. It improves filter performance, fast dissolving. Suitable for vinyl pools and spas. We opened the pool in the beginning of May, so of course it needs chemicals to get it going. We started with a shock treatment first. It worked perfectly. Says you can go swimming in as little as 15 mins after. We waited just to make sure it was dissolved. The product was dissolved at 15 mins but our pool is a nice size so we gave it an hour and a half. We used it accordingly to the directions and size on the box. Water is super blue and even cleaner. Tested it and our numbers are where they should be. I definitely would recommend this product for opening and closing off your pools. It absolutely works!!

Miracle working shock!

I love the Clorox Shock Clear for our pool! It works wonderful. Our pool was heading towards green due to rain & neglect but this cleared it. I added it to the pool and could see it start to work right away. Definitely recommend for keeping your pool maintained.

Long time user won’t use anything else in my pool

I’ve been using Clorox shock for a few years now I can’t say how easy my pool has been to take care of from top to bottom. I have less maintenance and downtime than I have in the past. Water is always clear and I use less shock. Every once in a while when I run out, I’ll go get it different brand and it seems like I have to use so much more shock

Fast dissolving

Clorox Shock dissolves quickly and clears out organics in the pool water fast. Regular use and keeping the correct chlorine levels prevents algae buildup and it doesn’t take long for the pool to be safe for swimming.

Clorox Shock Clear for Clean, Safe Swimming Pools

I have an 18′ above ground pool and these Clorox 4 in 1 shock treatments are just what any pool owner needs to get your water clear of bacteria and algae. After applying, you only need 15 minutes before going into the pool which is great when you have anxious kids! I like that it disolves quickly and can be safely used on vinyl as well as in ground pools. There are 6 to a box and usually only takes one treatment to get my pool ready for summer and maintained during heavy use or rain storms. Always good to have on hand!

Great Shock

This shock seems to do a great job clearing up my water and keeping the algae down. I like to follow it up with clarifier later the same day. I usually use a quarter or half bag at a time. Works better than the off brand shock

Always my “on-hand, go to” product.

Clorox Shock Clear always does the trick. I’ve had my pool for just over 4 yrs. Since Day 1, I’ve only used Clorox products. The products do a wonderful job and are moderately priced in comparison to the other brands. I keep Clorox Pool&Spa Shock Clear on hand year round here in Florida. The shock clear helps leave the pool crystal clear, free from algae and bugs like pool mites. It’s easy to use. Just disburse into the water and let the filters run for the day. I highly recommend this product and the Clorox lines of pool chemicals.

Can’t go wrong with Clorox Pool Products

I have been using Clorox Pool Products for the past several years and always have great results. I keep several boxes of the Clorox Pool & Spa Shock on hand throughout the pool season and use according to the directions. It has kept my pool sparkling and clean and levels in check. I trust the brand name and recommend to anyone. I am glad that my local stores keep the product in stock.

Good but may stain your vinyl pool.

It is good to use but I prefer liquid mix then the granulated powder. This is because it takes time to dilute in the water. I accidentally dumped a 1/4 cup before on my old pool and it did stain my vinyl pool. If you have it, make sure to have your pool churning if you are going to use this.

Season opening shock

I received this product right before I removed the winter cover from my pool. When I did remove the cover the water that I had in yhe pool was pretty green. I used this product to treat the water as a preliminary shock treatment and overnight I could see a noticeable difference in the appearance of the water in the pool. I wil add more water and shock again and I believe that it will clear up to the point that I can continue with the opening process.

I only use Clorox shock in my pool. It keeps the water clean and fresh. I’ve never had a problem with algae or bacteria. I’ve tried a few other brands and they never seem to last, making me shock it twice as much as I would have to with Clorox brand. And the price is the same.

Worked as it should without any hassle

I just opened my pool from winter and it was still clear but algae on the bottom. I brushed the bottom and shocked with Clorox shock and within 3 days of filtering my pool and vacuuming the pool is beginning to look a lot like summer!! This product is a great shock treatment for clearing out the algae and I will definitely be putting it on my supplies list for additional treatment throughout the summer. Thank you Clorox for a great product.

Cloudy to clear in under a week.

When I went to “open” my pool this year it was so cloudy i couldnt see 1/2 down the steps and the pool vac could not be seem. I put open in quotes because im in central florida so my pool is never really closed, just in a holding pattern for 2 or 3 months. My poolbwas cloudy this year because i neglected to clean my salt cell. After cleaning my salt cell i still couldnt get the water clear until I added this shock. Within a couple hours it was starting to clear and within a day it was almost back to normal!

I’ve been using clorox salt pool shock oxidizer but it has been difficult to find. Tried this shock and results seem to be the same. Keeps pool water clear.
