The Best Way to Use Chlorine Tablets to Clean Your Pool Water

Here’s Everything You Need To Know

There are a lot of responsibilities that come with owning a pool. One of which is cleaning the water regularly of contaminants, algae, leaves, debris, bugs, and other nasty things. This can be a learning process if you’ve never done it before. Skimming the water of its bugs and leaves requires the right tools and techniques. The same goes for eliminating algae and other microorganisms.
 
If you want to make the greatest impact on the sanitization of your pool water, then you need to pay attention to the water chemistry. The fastest and easiest way to sanitize the water is to add chlorine tablets to it. This is a chemical which every pool needs to stay clean.

The Benefit of Chlorine Tablets

Why use chlorine tablets instead of regular chlorine? For one thing, it is easy to administer the chlorine tablets into your pool water. The chlorine from the tablets does not get dispersed all at once. Instead, it is gradually dispersed and spread more evenly throughout the water. That is a benefit you won’t find with chlorine granules.

The Importance of Putting Chlorine in Pool Water

Chlorine is highly effective at sanitizing pool water, and it doesn’t cost that much money either. Chlorine can eliminate bacteria, viruses, algae, and other microorganisms in order to keep all the swimmers safe.

The Proper Amount of Chlorine to Add

The average swimming pool should have a chlorine concentration of between 1 ppm (part per million) and 3 ppm. This is the safest way to kill microorganisms in your pool without irritating the human swimmers at the same time. After all, excessive amounts of chlorine could contribute to certain symptoms like throat irritation, eye irritation, and even lung irritation.
 
To determine if the proper amount of sanitizer is in your pool water, you must conduct tests on the water using test kits or test strips. These testing products will not only tell you how much chlorine is in the water, but also how much of other chemicals are in the water too. Based on the results, you can adjust the water chemistry appropriately.

Selecting the Best Chlorine Tablets

Chlorine tablets are available in different sizes, 3 inches or 1-inch. The best choice is the 3-inch chlorine tablets because they’re bigger, popular, and sometimes even cheaper than the smaller sized tablets. One 3-inch chlorine tablet is powerful enough to clean 5,000 gallons of pool water. You could actually save more money by using fewer tablets.
 
First, do you know the volume of your swimming pool? If not, check with the pool manufacturer or installer to get this information. There are pool calculators on the internet that you can use as well.
 
Once you figured out the volume, you will know how many chlorine tablets to add. Always round the water capacity upwards to the next 5,000 gallons. For instance, if your pool has a water capacity of 17,000 gallons, then you would use four 3-inch chlorine tablets. But if it has a capacity of 15,000 gallons, you would only use three 3-inch chlorine tablets.

The Top 4 Methods for Adding Chlorine Tablets to Pool Water

Chlorine granules are easy to administer to the water because they’re just added directly. You may think that you can do the same thing with chlorine tablets. However, it is not a good idea. There are some better options for adding chlorine tablets to pool water. They are as follows:

1) Floating Chlorine Dispenser

Chlorine tablets are placed inside of the floating chlorine dispenser. The dispenser is placed in the pool water and gradually disperses chlorine out. Not a lot of maintenance is involved, making this a convenient way to clean your pool water.
 
The only downside is if there’s a pool liner installed. Floating dispensers may get stuck somewhere and then disperse excessive amounts of chlorine in only one area of the pool. Not only will this discolor the water, but it could leave the pool liner damaged too. Worst of all, the chlorine circulation throughout the pool will be ruined.
 
So, consider all this if you have a pool liner installed. .

2) Pool Skimmer

Add chlorine tablets to the skimmer basket. As the filter runs, water passes through the skimmer and tablets quickly. This causes the tablets to dissolve a lot faster than they would in the floater. Then, while the return jets are on, chlorinated water flows back into your swimming pool and spreads everywhere evenly.
 
The one downside is that your chlorine tablets will keep on dissolving regardless of whether your filter is actively running. This could result in too much chlorine being added to your water and your equipment getting damaged as a result.
 
To avoid this situation, remove the remaining pieces of the tablets from the filter when it is not activated. Either that or you can have a variable-speed pool pump installed to keep the water cycled regularly.

3) Automatic Chlorinator

The Automatic Chlorinator is perhaps the best choice here. You can manage the chlorination levels of the pool water quite well without much effort. Just put the tablets in the chlorinator, select a chlorine level of between 1 and 3 ppm, and use chlorine test strips to verify the chlorine level. As you get more experienced, you’ll know which settings are the best for your pool.
 
Just make sure the pool water passes through the Automatic Chlorinator right before going back into the pool area. This will ensure the water stays chlorinated and clean.

4) Chlorine Granules

Chlorine granules are basically crushed tablets which are tiny enough to sprinkle into the water. Only use this method if you must clean smaller, localized areas of your pool water. It will take a lot of time to administer granules to every area of your pool because it would all have to be done by hand. That is why an automatic chlorinator is recommended as a more efficient and time-saving alternative.

Conclusion

As you can see, it is not too difficult to administer chlorine tablets to pool water. The method that you choose depends on you and the amount of time and money you want to devote to this task.
