What are Pool Chlorine Tablets?

Pool chlorine tablets are an essential component when it comes to keeping your pool clean and safe. These tablets work by releasing a steady flow of chlorine into your pool water, allowing for consistent sanitisation and disinfection. They’re easy to use and offer a more convenient alternative to liquid chlorine.

How do Pool Chlorine Tablets Work?

When you introduce a chlorine tablet into your pool, it begins to dissolve slowly. This slow release of chlorine ensures that your pool stays clean and free from bacteria and other harmful microorganisms. It’s important to note that the effectiveness of these tablets can vary depending on factors such as water hardness, tablet density, and solubility.

To ensure that your pool remains at its best, it’s essential that you regularly test your pool’s pH and chlorine levels. These levels should ideally sit between 7.2 to 7.8 for pH, and 1 to 3 ppm (parts per million) for chlorine.

Types of Pool Chlorine Tablets

There are a variety of chlorine tablets available on the market, each suited to different needs and pool types. Among these, Trichlor chlorine tablets are a popular choice, particularly for commercial pools. These tablets offer up to 90% available chlorine content and are stabilised, which means they are less affected by sunlight and temperature changes.

When selecting the right size of tablet for your pool, you’ll need to consider factors such as the size of your pool and the frequency of application. For example, if you have a pool that holds 350 gallons of water, a 1-inch tablet may suffice. However, for larger pools holding between 5000 to 10000 gallons, you may need to opt for 3-inch tablets.

Factors to Consider When Choosing the Best Pool Chlorine Tablets

When seeking out the best chlorine tablets for your pool, it’s not just about picking up the first product you see on the shelf. Various factors come into play that’ll help you make an informed decision. In this section, we delve into some of the key aspects you should consider.

Concentration of Chlorine

One key aspect to consider is the concentration of chlorine in the tablets. It’s important to remember that a higher concentration doesn’t always equate to better quality or effectiveness. Instead, it’s about finding the right balance. Too high a concentration might make the water irritating to skin and eyes, whereas too low might not effectively sanitise your pool.

Dissolving Rate

Another significant point to take into account is the dissolving rate of the tablets. Some tablets dissolve more quickly than others. Fast dissolving tablets might seem like a good option for a quick clean, but they can sometimes result in unbalanced chlorine levels. On the other hand, slow dissolving tablets maintain a steady level of chlorine, but they require more patience and planning.

Long-lasting Effects

Lastly, don’t underestimate the importance of the long-lasting effects of the chlorine tablets. Some products are designed to have a slow release, ensuring that your pool remains clean for longer periods. This means less frequent maintenance and more time for you to enjoy your pool.

Bear in mind that the best pool chlorine tablets aren’t always the most expensive ones. It’s about finding the right product that suits your pool’s needs and your lifestyle. As you consider these factors, you’re well on your way to making an informed decision that’ll help keep your pool clean, safe, and inviting.

Pros and Cons of Using Pool Chlorine Tablets


Ease of Use: You’ll find that pool chlorine tablets are quite simple to use. Just pop them in your pool’s skimmer, floater, or automatic feeder and let them do their magic. You won’t need to measure or mix anything, which is a significant advantage over using liquid chlorine.

Stable Chlorine Levels: Tablets help maintain stable chlorine levels in your pool. They release chlorine slowly, which ensures that your pool has a consistent level of chlorine. This slow release helps prevent fluctuations in chlorine levels that can lead to algae growth and other problems.

Cost-Effective: Over time, you’ll find pool chlorine tablets to be a cost-effective way to keep your pool clean. They last longer than liquid chlorine, which means you won’t need to replace them as often.


Potential for Over-Chlorination: There is a risk of over-chlorination when using pool chlorine tablets. If used excessively, they can cause high chlorine levels, which can lead to eye irritation and other health issues.

Not Ideal for Quick Chlorination: If you need to quickly raise the chlorine level in your pool, tablets may not be the best choice. They dissolve slowly, so they’re not ideal for shock treatments.

Requires Regular Monitoring: To make sure you’re not over or under chlorinating your pool, you’ll need to regularly check the chlorine levels. This means investing in a good quality pool test kit and taking the time to use it.

Remember, the key to a healthy, sparkling pool is regular maintenance and monitoring. With the right balance of chemicals, your pool can be a safe, inviting oasis all year round.

Tips for Using Pool Chlorine Tablets Effectively

Tips for Using Pool Chlorine Tablets Effectively

Once you’ve chosen the right pool chlorine tablets, it’s essential to know how to use them efficiently. Here are some tips to get the most out of your pool chlorine tablets.

Correct Dosage

One of the most critical aspects of pool maintenance is getting the dosage right. Over-chlorination can lead to health hazards such as skin and eye irritation. On the flip side, under-chlorination may not kill harmful bacteria and algae, leading to a dirty pool.

The ideal chlorine level for a swimming pool is between 1 and 3 parts per million (ppm). This level ensures that the water is safe for swimming without causing any health issues. It’s a good idea to use a pool test kit to measure the chlorine and pH levels in your pool. You’ll be able to adjust the chlorine tablet dosage based on the readings.

Proper Storage

The way you store your chlorine tablets can greatly affect their efficiency. Chlorine tablets should be stored in a cool, dry place, away from direct sunlight and other chemicals. Sunlight can degrade the chlorine, reducing its effectiveness.

Additionally, always ensure that the container is tightly sealed. This prevents moisture, which can lead to tablet degradation. Remember, safety should always come first when handling pool chemicals. Always wear protective gear such as gloves and goggles to avoid direct contact with the skin and eyes.

Regular Water Testing

Water testing is not a one-time task. It’s something you need to do regularly to maintain the optimal chemical balance in your pool.

Regular water testing helps detect any changes in the water chemistry. This can be due to factors such as rainfall, pool usage, and temperature changes. It’s advisable to test the pool water at least once a week. More frequent testing may be necessary during the swimming season or after a heavy rain.
