The 10 Best Pool Chlorine Tablets – 2020

1. NAVA 12000295 Chlorinating Tablets – Best Overall

NAVA 12000295

The Nava 12000295 wins out as our top choice on today’s list. There is plenty to like about this unit, not the least of which is the fact that all of the pucks are individually wrapped to guarantee that they stay in pristine, fresh condition.

This is especially handy for the fact that the bucket is quite large. This is a 50-pound container, which means you might have it around for a while.

We also quite like the fact that these are slow-release pucks. The cleaning chemicals release over a period of several hours, which means that the water of your pool will stay consistently clean as long as you are using the pucks.

You will want to note that this is one of the pricier options on our list. The quantity and quality make the money worthwhile but if you’re a budget buyer this probably won’t be the option you chose.

Pros
  • Slow-release
  • Individually wrapped pucks
  • 50-pound container
Cons
  • Fairly pricey

2. Kem-Tek Chlorinating Tablets – Best Value

Kem-Tek 2815-6

Up next, we have the best pool chlorine tablet for the money. The value-minded buyer will appreciate the chance to save money with the Kem-Tek. There is plenty to like with this offering.

Like our top choice, it is a slow-release unit, which means that your pool water will be consistently fresh. The chemical compounds of the pucks have also been specially fortified to withstand the rays of the sun. UV light can reduce the effectiveness of chlorine, which offsets the effectiveness of your equipment.

That said, it is important to remember that this is a very small container. The last package that we looked at was 50 pounds. This unit is a measly 1.5 pounds. As a consequence, it is well suited for smaller “pop-up” pools.

However, if your cleaning needs are more modest, this is a great way to get everything you need in an affordable package.

Pros
  • Affordable
  • Fortified against the sun
  • Slow release
Cons
  • Very small package

3. Rx Clear Granular Chlorine – Premium Choice

Rx Clear

Next, we have a more moderately priced package that is still well equipped to handle the needs of larger pools. This is a50-pound bucket available at an affordable price.

All of the pucks in this unit are prepackaged and separated, both to keep them fresh, and to make it easier to figure out how much to use at a time.

Finally, it is also a very potent mixture. The pucks are all 99 percent chlorine, with very little in way of additives. Consequently, the chemicals are added to the water of your pool fairly slowly, making them a great way to keep your pool clean over longer periods.

The only real issue to bear in mind is that many feel the chemicals are too potent, with some users saying they found it very irritating to their skin. Granted, this is a very subjective complaint that could be a product of dosing mistakes. Still, it is something to be aware of.

Pros
  • Affordable
  • Slow release
  • Very powerful
Cons
  • Some report skin irritation

4. In The Swim Pool Chlorine Tablets

In The Swim BLZ-5626

In The Swim is an affordable package that has been pre-sized to be used with floating chlorine dispensers or more automated feed symptoms.

Like most of the products we’ve seen to this point, the pucks are slow dissolving, and they have been stabilized for UV light, as well as other variables that can limit the effectiveness of chlorine.

Many users have reported that these pucks seem to have made their pool look cloudy, especially in the hours immediately following their implementation. This is a fairly common occurrence with chlorine, and not necessarily symptomatic of a major problem.

Still, many people consider chlorine to be an integral element of their pool’s appearance as well as its overall health so this is something to bear in mind.

Pros
  • Moderate price
  • Fortified for UV rays
  • Slow dissolve
Cons
  • May make pool a little cloudy

5. Swim Best Swimming Pool Chlorine

Swim Best U009050050

The Swim Best Chlorine pucks are sized to be three inches in diameter, making them a good fit for most floating chlorine dispensers as well as automated systems. As with the rest of the options on our list to this point, the pucks are individually wrapped, which makes it easy to portion out the right amount of chlorine.

It’s also fairly affordable, which is handy for buyers on a budget. There have been some user complaints that the pucks deteriorate in the bucket. In other words, pucks that were intact when the bucket was purchased become crumbled and diluted a few months down the line.

Crumbled chlorine pucks actually do still work, but they can be harder to portion out, and just generally inconvenient to handle.

Pros
  • Affordable
  • Pre-packaged
  • Properly sized for most situations
Cons
  • Some report pucks breaking up in bucket

6. Clorox 22005CLXW Chlorinating Tablets

Clorox 22005CLXW

The Clorox package will be an economical option that is specifically optimized for smaller pools. Because the bucket is only five pounds in size, it won’t be very practical for people with larger backyard pools, but it represents a good opportunity for budget buyers.

That said, it has more going for it than just its price. It’s also fairly potent and needs only to be administered twice a week to keep your pool looking nice and pristine.

Many users are reporting that the structural integrity of the pucks is very poor. Some say that many of their pucks arrived broken up. As mentioned earlier, broken pucks are still usable, but they are a little tedious.

Pros
  • Affordable
  • Potent
Cons
  • Puck structure is low quality

7. Star Plus Chlorinating Tablets

Star Plus

Star Plus Chlorinating tablets are optimized for bigger pools. Their 50-pound bucket is moderate in price, which will be good for the buyer on the budget, and the product is ultimately very effective.

These are slow dissolving pucks that will do well to keep your pool looking good over time. They also tend to last a long time, which means you will only need to apply the chlorine once or twice a week to maintain effectiveness.

The pucks are also sized to work well with floaters, and any other administering system you might have in your pool.

We didn’t find too many cons, but we did notice that the pucks tend to create cloudy water. Again, this isn’t an enormous problem, but it is something that most pool owners will want to know.

Pros
  • Moderate price
  • Slow release
  • Works for a long time
Cons
  • Cloudy water

8. hth 42009 Chlorinating Tablets

hth 42009

The hth 42009 advertises itself as a 4-in-1 cleaner. It is made to protect against the sun and algae while also sanitizing your water and just generally making the pool look nice.

Budget buyers will also want to bear in mind that it is one of the more affordable products that we have featured on the list today. If you own a smaller pool and are on a limited budget, this package represents a real value opportunity.

That said, there are some things that it doesn’t do so well. For one thing, the pucks tend to break up very easily. The impact of the puck also seems to be very short. That means that you may find yourself applying additional chlorine more often than you would with other products on our list.

Pros
  • Affordable
  • 4-in-1 protection
Cons
  • Not very long-lasting
  • Pucks tend to break up easily

9. Doheny’s Pool Chlorine Tablets

Doheny's Pool

Second to last, we have the Doheny’s chlorine tablets. This product is fairly affordable because it is a 50-pound container and the pucks are sized at three inches, making it compatible with most chlorine distribution systems.

However, the performance does leave something to be desired. The pucks tend to break very easily, while also leaving the water very cloudy immediately after use.

The tablets aren’t unusable by any means, and they will ultimately ensure that your pool is safe to use. However, for a little bit more money you can get something sure to work better.

Pros
  • Affordable
  • Sized for most chlorine distribution methods
Cons
  • Not very durable
  • Makes water cloudy

10. Pool Mate Jumbo 3-Inch Chlorine Tablets

Pool Mate 1-1404

We close out our list with the Pool Mate. Price is definitely the main selling point with this unit. It is actually the most affordable pick on our list today, though this is partially because it is only four pounds in size.

Unfortunately, it doesn’t stack up very well compared to the other options featured in this article. The pucks themselves are poorly composed and tend to break apart easily. They also tend to make the water cloudy, and they just don’t last as long as we’d like to see.

If you are on a restrictive budget, this will be a fine way to keep your pool clean. However, if you have money to spend you might think about one of the other choices on the list.

Pros
  • Affordable
Cons
  • Not very sturdy
  • Cloudy water
  • Doesn’t last for very long

Buyer’s Guide

We’ve covered quite a few products. Now it is time to help you choose between them. Read on for some buying considerations.

Size

Most pucks are sized to be three inches. Foremost people, that’s the size you’ll want to stick with. Why? The majority of chlorine distribution systems (floaters, skimmers, etc.) are sized to work with three-inch pucks. Going with this size will ultimately save you a headache down the line.

Pre-packaged

Though not necessary, it can help to have your pucks pre-packaged. For one thing, it protects them from the degradation that tends to occur over time. It also tends to make it easier to portion out how much chlorine you need to use per session.

Quantity

You may have noticed that the size of packages will vary. We looked at some options that were only a pound, and others that were 50 pounds.

The more you buy, the better the deal you will ultimately get. Just like many other products, you get a better price per ounce by buying in bulk. It may seem excessive to buy 100 pounds of chlorine, but don’t worry, you will use it eventually!

Conclusion

What did you think of our chlorine puck reviews? Hopefully, you already know which product you will be taking home. If not though, we might be able to bring a little bit of clarity to your decision. Buyers that don’t mind spending a little bit more on a high-quality product will appreciate our top choice, the NAVA 12000295 Chlorinating Tablets.

However, you can also enjoy a high level of performance on a budget by going with our best for the money pick, the Kem Tek.

Of course, by now you know a good deal about chlorine tablets. Feel free to make your own informed decision!
