How To Use Chlorine Tablets for your Pool

The complete guide to Chlorine Tablets

If you are the owner of a pool, then you are already aware of how much pleasure they provide, but you also know that taking care of a pool and maintaining it properly takes some effort and is quite a responsibility. If you are the type of person that prefers a pool that is in pristine condition when you have friends over, then it is important to have it in top form at all times. At the end of the day, nobody wants to swim in a pool that is dirty and is full of debris.

In order to keep your pool in top shape, the duties will include water skimming, wall scrubbing, vacuuming the pool floor, filter cleaning, and a few other duties that will keep the pool and the water in it visibly clean. But if you thought that was all, think again as there are more issues involved with pool care that every owner should be aware of – specifically using chemicals to keep the pool water clean and sanitized.
One of the biggest misconceptions that should be addressed is that just because a pool appears to be clean, that doesn’t mean it necessarily is. Water that is clear in appearance can still contain a substantial amount of bacteria, invisible residue, and other contaminants that can make it unhealthy to swim use. This is exactly why you need to learn about chlorine tablets and how to use them to maintain a proper condition for your swimming pool . They are not that difficult to use, but there are some rules that must be adhered to in order to sure there is no damage to your property. If used incorrectly, you may end up spending lots of money to fix a problem that easily could have been avoided. We will provide a quick review of what chlorine tablets are, how to use them, and what to expect of them regarding your swimming pool.

What Are Chlorine Tablets?

Chlorine tablets are one of the safest and most affordable ways that users can clean their pool. These tablets dissolve and release chlorine into the swimming pool water as they gradually get smaller. They are increasingly popular with pool owners as they are so simple to use – all you have to do is place them in the water and then sit back and let them do what they have been formulated to do. Knowing where and how to place them in your pool, however, dictates how effective they are in producing a great end result. There is no exact measure when it comes to the chlorine tablets, but a few tips will guarantee that your efforts are not in vain.

Why Chlorine Tablets?

As mentioned before, chlorine helps to kill bacteria and other types of germs and contaminants that are prone to pop up in swimming pools and cause potential health hazards. With chlorine added, pools receive a sanitization process as soon as the product hits the water, breaking down once combined with H20 to form hypochlorite ions and hypochlorous acid. These two compounds are quite active in sanitizing the water through the oxidization of the pool’s contaminants. The hypochlorite ions slowly release and oxidize over an extended period while you can expect instant action from hypochlorous acid. These together will ensure that your swimming pool is hazard-free and removed of all contaminants.

Breaking Down Chlorine Tablets

Chlorine tablets are available in two sizes: tablets that are 1 inch and tablets that are 3 inches. It is advised to invest in chlorine tablets that are 3 inches, since it only takes one tablet to provide optimal results for approximately 5,000 gallons. But it should be noted that a 1-inch tablet will have less chlorine, making it ideal if you own a small pool or spa.

Aside from the size, there are other differences between the two that come down to the ingredients they contain. For example, some tablets can be labeled as either unstabilized or alternately, stabilized referring to the cyanuric acid content. Also known as CYA, this acidic agent protects chlorine from burning due to the sun’s rays. If you have stabilized chlorine that has CYA, it will last far longer and also in sunlight. Chlorine that is unstabilized doesn’t have any CYA included, which effectively reduces its potency and means that it will burn away after exposure to the sun within a few hours. Note that outdoor pools should use chlorine tablets that are stabilized.
There are some tablets that come with a few other chemicals, including those like clarifiers and algaecides, both of which you can add later and separately as needed, depending on your budget.

How to Use Chlorine Tablets

One of the first questions that you may have are how many of these tablets do you need to use for your swimming pool? Well, that all depends on the measurements of the pool in question. The best answer is that you can estimate from 1 chlorine tablet for approximately 5000 gallons and then add another tablet after every 2000 to 3000 gallons for optimal results. In other words, four tablets are able to clean a pool that holds up to 20,000 gallons of water.
Adding Chlorine Tablets to Your Pool
This is the most critical part of the cleaning process, because it is important that the tablets not hit the bottom of the pool. Doing so can lead to adverse reactions that will cause damage to your pool, including possibly permanents stains as well as bleach liners. Here are some items we suggest for the best cleaning methods”
A Floating Dispenser
These little plastic containers are quite simple to use and are able to hold the tablets inside and gradually dissolve to clean the area. Be careful that these do not remain in one area of the pool or even in corners as they will not be able to effectively treat the entire area. These are the manual method, which means you will have to pay a bit of attention to them throughout the process for optimal results.

With the skimmer method, all you need are the tablets, making it the easiest option available. A skimmer will ensure that leaves, debris, and other contaminants are blocked out, plus they are a great way to dispense chlorine. Water will float through the skimmer line, directly into a a filter, then the heater and lastly back to the pool. This constant stream means you get the best distribution and dissolving of the chlorine tablets possible. A skimmer is able to effectively spread the chlorine in an even way, better than a pool dispenser can.

But bear in mind that any tablets that are remaining in a skimmer will continue to dissolve, so it is important not to leave them sitting as this can lead to water that is too concentrated and highly chlorinated, effectively causing corrosion to the pipes and any other pool equipment you use for maintenance. The best suggestion is to use a schedule for running the pump, and then be ready to remove any tablets that are almost completely dissolved. For those pool owners that possess a speed pump that is single, try switching speeds so that you can reduce your energy bills and maintain an affordable cleaning process.

Automatic Chlorinator

This is best method for using chlorine tablets as it allows for more precision and speed as the tablets dissolve. An automated chlorinator is a large container that is filled with the tablets and has a knob used to adjust the feed rate. Typically, these are placed near the heater and directly before a return line. Simply load it, set the rate, and then wait for clean water. Not only will it save you loads of time, but you will get the most value for your investment.


Granular chlorine is basically just tablets that are crushed up, so if you are in a time crunch, simply crush some tablets until they form a smooth powder and then evenly distribute them the resulting granules throughout the pool. The chlorine won’t be as long-lasting using this method, but you will get quicker results and this is a great way to sanitize the water rapidly.


This is essentially all of the information that pool owners will need on chlorine tablets to effectively clean their pools. Most owners will probably need only about 2 to 4 tablets every week, and you only need to use a skimmer if you don’t want any additional steps in the process. Then, just leave it up to the pool pump to produce the preferred result.

Remember that you have to use the proper tablet sizes depending on the measurements of your pool, with stabilized 3 inch tablets ideal for outdoor pools and 1 inch unstabilized tablets best for small pools. Using the guidelines mentioned, you will be able to maintain a pool that is perfect for your personal use and for your friends and family.
