Buyer’s Guide- Best Chlorine Tablets for Pools

Picking the right product as per the appropriate application will give you great results and make your pool clean & healthy.

I mention the major three things that you need to consider when you buy chlorine tablets for your pool in this section.

Chlorine Tablet Types:

As discussed earlier, stabilized chlorine tablets maintain a consistent level of pH & chlorine in the pool. It is suitable for outdoor pools.

The unstabilized chlorine tablets give quick results but the effectiveness deteriorates in the presence of heat and sunlight.

Tablet Size & Dosage:

There are different types of chlorine tablets available in the market but the most common size is 3 inches & 1 inch. The size you should choose depends on the volume of the pool and the size & type of dispenser.

You can get the information on how many chlorine tablets required as per the gallons of water on the label of the product provided by the manufacturer.

Tablet Packaging:

You regularly require chlorine tablets for your pool so you should choose a bigger packing size to save your money & time. On the other hand probability of broken tablets is increased with the bigger size. In this case, if you have enough storage facility available then buy a small or medium-size package.

Always try to pick a package that comes with a child lock facility.

Percentage of Chlorine:

Trichlor based chlorine tablets contain 90% of active chlorine. It means you require a small quantity to chlorinate your pool. Some product contains cyanuric acid additive means, it will last longer in the sun-light. 

How to Use Pool Chlorine Tablets?

Basically, there are four ways to add chlorine tablets to your pool. Let’s discuss each of them in detail.

1. Directly Sprinkle Tabs into The Pool

As the name suggests you can directly sprinkle the tablet across your pool. Before sprinkling the chlorine tablets, you should calculate the required quantity according to the volume of your pool water. 

As per the thumb rule, One chlorine tablet is required for 5K gallons of pool water volume, and for better clarification please read the manufacturer’s instructions. You should also take some safety precautions while sprinkling like wear gloves and goggles to protect your skin & eyes.

After sprinkling the chlorine tablets start the circulation of pool water and leave it to spread evenly.

However, This is not the best approach to add chlorine tabs to water because it has some limitations like chlorine may not spread evenly across the pool so that you can’t get the exact concentration of chlorine in your pool.

2. Chemical Dispenser Method

You can also dose the chlorine tabs to your swimming pool using a chemical dispenser of a floater. Simply open the floater and add the chlorine tablets to it. Leave the floater to the pool and wait until the tablets dissolve.

The limitations of this method are if the dispenser stuck on one side of the pool then the remaining part of the pool left ineffective. In addition to that dispenser doesn’t allow water to pass through it so the proper distribution of chlorine isn’t possible.

3. Using Skimmers

First, start the water circulation for about 10-15 minutes using a pool pump to clean the water circulation lines.

Add the chlorine tablets to the skimmer. The filter works to quickly move the water over the tap to dissolve it slowly. The skimmer carries the dissolved chlorine tab through a return jet, allowing the chlorine to spread evenly throughout the pool.

Finally, Cover the skimmer & allow it to run at least 2-3 hours for proper mixing & circulation. Take out the container after turning off the pump.

4. Automatic Chlorinator System

This is the best and most effective method to add chlorine tablets to pools. As the name suggests automatic pool chlorinator automatically dispenses chlorine into your pool water as per the requirement.

You only need to set the desired ppm in the chlorinator & it does the rest for you to maintain the chlorine level in the pool.

Benefits of Chlorine Tablets for Pools:

In this section, I will cover the benefits of chlorine tablets against liquids and other types of chlorine-based cleaners.

  • Chlorine tablets come in nice big size packaging so that it will last up to the entire season. You don’t need to spend your money to keep buying other chlorine-based cleaners regularly.
  • You don’t need to manually sprinkle liquid or powder-based cleaners to all-around your pool. Just, drop the chlorine tablets using pool pumps and it will automatically spread around the pool.
  • Chlorine tablets are super easy to measure. You don’t need to weigh or mix with other cleaning chemicals. Drop the right numbers of tablets to the pool which is recommended by the manufacturer.

Types of Chlorine Tablets for Pools:

Chlorine is a strong oxidizer and highly reactive chemical. There are two forms of chlorine tablets available in the market namely stabilized & unstabilized.

In this section, I will cover the advantage, disadvantages & differences between them.

Stabilized Chlorine Tablets:

In the presence of sunlight UV rays reach the pool and water heats up so the chlorine dissolved quickly. 

As an effect, you can notice the drop in chlorine level. You need to add more chlorine to maintain the desired level of chlorine & ultimately it costs you more money.

To get rid of this issue, Most of the manufacturer adding stabilizers to stabilize the chlorine tablets. Stabilizers slow down the dissolving rate of chlorine also in the presence of sunlight.

On the other hand, a high level of stabilizers makes the sanitization process slower than desired. It is the best solution when you want to maintain steady pH & chlorine levels in the pool.

Stabilized tablets have a long-lasting effect than unstabilized chlorine tablets. It is the perfect solution for outdoor pools.

Unstabilized Chlorine Tablets:

Unstabilized chlorine tablets are exactly the opposite of stabilized ones. Due to the absence of stabilizers, it will be dissolved faster in pool water.

In the presence of sunlight, the efficiency of unstabilized chlorine tablets deteriorates. Now, the question is why should I use them?

Unstabilized tablets are a good solution for indoor pools where you apply all routine treatments to make your pool clean from contaminants. You can get quick and effective results in no time.
