5 Best Pool Shock Brands on the Market (Review My Favorite)

Best Pool Shock

Safe Swimming Pool Shock Treatments

That’s what you want when you have 1,000s of gallons of water in your backyard with kids and animals splashing around in it.


I’ve spent the last 10+ years skimming out ducks, rats, mice, lizards, bugs, spiders, and other critters – dead and alive from my swimming pool…

And every year since 2007, I’ve spent several hundred dollars ($200 – $300) on pool chemicals, such as 3-inch chlorine tablets, pool shock, water conditioner, algaecide, and muriatic acid – all just to keep nasty organism from living in the swimming pool water.

You name it, and I’ve tried it – every brand of pool supplies sold at Walmart, Lowes, Leslie’s and on Amazon.

I’ve learned my lesson when it comes to buying cheap pool chemicals.

cheap pool shockThe one important pool supply I definitely don’t skimp on is the shock.

I buy the best pool shock I can afford because by far it’s the most important pool chemical along with chlorine tablets for keeping my swimming pool clean, clear blue, safe for swimming, and odor and algae free.


After over a decade of do-it-yourself swimming pool care, I’ve tried every flavor of pool shock there is from HTH, Pool Essentials,  Aqua-Chem, Kem-Tek Super Shock, DryTec, In The Swim, to the Leslie Pools brand, and the best I have found is Clorox Xtra Blue.

That’s right, Clorox Xtra Blue is the best!

As a DIY, I searched high and low for a product that would save me time and money because I wanted:

  • The best price on pool shock (anything less than $5 per treatment was a deal).
  • The best shock to use for an in-ground pool that had been re-plastered (with and without chlorine).
  • Pool shock products for Arizona’s hard water with high levels of alkaline (liquids or granules).
  • Discount pool shock or coupons that I could use at Lowes or at Leslie’s Pool Supply.
  • The strongest shock available that killed any organism – but safe for home use since I was only doing DIY pool maintenance.

How To Sock Your Pool

Benefits of Pool Shock Transcript

The weather is right and the family is ready to use the pool, but what about that strong chlorine odor? We’ll show you what to do about it. Time to clean the gutters. Climbing the ladder and dealing with leaves, bugs, and muck is a tiring and potentially dangerous chore. Not anymore. We’ll show you an innovative solution that will save you hours of nasty work. Your car, it’s another space you live in just about every day. Today, we’ll show you how to make your driving spaces stylish and more comfortable. This is the show all about you and your space.

Your home and surroundings. We are Designing Spaces. (Music) Do it yourself pool care is now simpler than ever. Once you understand a few basics and have the right tools it can be shockingly easy. Designing Spaces goes poolside to see for ourselves. Take a look. Designing Spaces got together with Rebecca, New Products Manager for the Clorox Pool and Spa brand to show Melia some simple pool care tips that will help her with her problem. Was I glad to see Rebecca? I could really use some help understanding why my pool acts up sometimes. It seems like Melias’ a little bit shy when it comes to using chlorine. I need to get her comfortable with how to maintain the proper levels. (Music). So what’s going on? I’ve been adding chlorine to my pool and now I’ve noticed this really strong chlorine odor. Am I overdoing it? To be honest, that smell could mean you’re not adding enough chlorine.

Not enough chlorine? Was I surprised? I figured because the pool was clear everything was fine. The clearness of the water does tell you a lot about the chemistry, but it’s not going to tell you everything. Have your kids been using the pool a lot? With the weather getting warmer, yes. Yea, I figured it was being used regularly and that will actually use up the chlorine and could lead to that chlorine odor. When’s the last time you tested? Like I said, I figured the pool was clear so everything was fine. Yea, well we should definitely test before we go to the store. Can you download the Clorox Pool app? Sure. What Melia doesn’t understand is that after chlorine is used it can linger in the pool.

Weekly use of the shock will help break it down so you don’t run into that strong chlorine odor she’s having. (Music). Ok, so just search Clorox Pool in the app store. Ok. Perfect, there it is. And now we’re going to set up your profile. So put in how many gallons of water you have. Ok. Great and then it’s a regular chlorine pool, of course. And final liner. Perfect, that’s it. So now we are ready to test the water. Awesome. So all your going to do is take one test strip and dip it into the water at elbows depth and that will give you the best reading. So you dip it all the way in, your going to shake once, then lay it down on the grey card. So do the Multi-Use Smart Strips help me know when to shock? Well, I’ll show you. So if you open up the app and go to the test your water section. Ok. Your just going to line up those lines with the test strip. Ok. Just like that, perfect. You see it went green, so now it’s analyzing.

Ok. So now we can see that your total chlorine is higher then your free chlorine and what that means is that there is used chlorine in the pool and that’s when you know how to shock. So this is the Clorox Pool and Spa Chemical set. Ok. And the first thing we need is Shock Extra Blue. And it conveniently comes in our new easy open, easy pour shock bottles. I think you’re going to need a few so we’ll go ahead and grab a six-pack. Ok great. Just put it in the cart. Yea. Perfect. Ok. (Music). So the other product you need is the multi-use smart strips which should be used weekly to help test your chlorine levels and these will teach you when you should shock the pool.

We’ll go ahead and add those and head out. Thank you so much. Yea. We need to pick up a Clorox Pool and Spa Step Three Shock, like Shock Extra Blue. I also picked up the My Pool Care Assistant Multi-Use Smart Strips so she can watch her levels and maintain her pool in the Clorox Pool and Spa comfort zone. So we have Shock Extra Blue, which is what the app recommended to cure your used chlorine. It’s a six in one formula that has Algae killing crystals, which kill any type of algae. It also kills bacteria, removes contaminants, and clears cloudy water and just what the doctor ordered, it reduces chlorine odor. When do I use it, how often? Well, Shocking is step 3 in the Easy One, Two, Three Pool Care Brand System and should be used weekly to maintain chlorine levels. We also recommend you shock more frequently after high heat, heavy rains and if you use the pool a lot. How long do I have to wait before I let anyone go into the pool? That’s a great question, and one of the great things about Shock Extra Blue is you can treat and swim in just 15 minutes.

But we do recommend you test before you swim to make sure your chlorine doesn’t exceed four parts per million. 15 minutes, wow, that’s great. My kids are going to love that. How do I shock the pool? So the app recommended you add three pounds using the new easy open, easy pour shock bottle. Ok. Wow, I really like this bottle. It’s really simple to get the shock to go where I want it to go. I was so happy to discover how simple it was to test and treat my pool with the Clorox Pool app.

I heard about shocking, but I hadn’t given it much attention. But now, my have things changed. Thank you so much, Rebecca, for showing me what to do. I now know I do not have to be shy with chlorine. You’re so welcome. Just remember to test your water regularly and monitor your chlorine levels and don’t forget to shock weekly. All of us on the Clorox Pool and Spa Products Team want pool owners to know that with Simpler and Smarter Pool Care Brand System you can save time and money on pool care.

My favorite pool shock has an easy to open and pour bottle!

Best Pool Shock On The MarketNot only does the Clorox Xtra Blue easy-to-open-bottle make it simple to add shock to the water but it really does the job of keeping the water clear, keeps the algae from growing, and helps lower the need to add as many chlorine tablets each week.

This is a big deal in Arizona where the pool water temperature gets in the 90s when the pool deck is 125+ degrees; perfect for supporting an ecosystem of bacteria, bugs, ducks, and algae…

BTW, when I say easy-to-use-bottle, I mean it because if you’ve ever tried to rip open a bag of super shock with your teeth, you know what I’m talking about.

It doesn’t make sense why the manufactures of pool shock don’t think about making it easy to tear the end of a bag of shock but they don’t – I digress!

So without any more of my rambling, let’s see which is the best pool shock on the market to buy for DIY pool maintenance

Warning About Poop In The Pool Water

On any given day in your chlorinated pool, you’re just one toddler diaper or animal poop away from dangerous recreational water illnesses.


These illnesses are caused by organisms such as Cryptosporidium, Giardia, and E. Coli, as well as symptoms such as severe diarrhea, which will all make you and anyone swimming in your contaminated pool water very sick.
