If you are a pool owner, it is plausible that you have already wondered what are the best chlorine tablets for the swimming pool. These chlorine tablets are added to the swimming pool to kill bacteria, viruses, and protozoa.

Provided you don’t know it yet, chlorine is the main reason why your pool water tastes funny. However, chlorine goes way beyond than just making your pool water taste funny.

Why your Pool Needs Chlorine tablets?

Have you ever seen a Hollywood movie with a perfect, sparkling pool water? The reason behind that crystal clear pool water are the chlorine tablets. Provided you have injected an optimum amount of chlorine into the pool, it will kill dangerous microorganisms which cause ear infection, athlete’s foot, gastroenteritis, and Legionnaires disease.

These bacteria seem to form in stagnant water. Consequently, it becomes customary for you to remove them through chlorination. Therefore, if while using your pool, it is crucial that you know the usefulness of chlorine tablets. After adding chlorine into your pool, you must know about how to keep its chlorine level up.

Different Types of Chlorine

There are two types of chlorine which are available in the market: stabilized and unstabilized chlorine. While the stabilized chlorine is used outdoor swimming pools, the unstabilized version is best for indoor ones.

Reason? As suggested by its very name, the stabilized chlorine lasts longer in the swimming pool. Hence, under the watchful eyes of the sun, it will protect your water, while chlorinating it at the same time. Consequently, it can last longer even in broad daylight.

However, as for unstabilized chlorine, its effectiveness diminishes under sunlight. Therefore, it is often recommended to use it for indoor swimming pools. However, if you carry out chlorination at night, you can use the unstabilized chlorine for outdoor pools as well.

What is the best time for chlorination?

There are some people who argue that you can add chlorine at any time of the day. As you might expect, there are others who claim that chlorination should be done at night. Reason? It’s simple: when added at night, you’ll give chlorine ample time to function and kill the bacteria.

While stabilized chlorine shields from sun rays, it cannot block them. Therefore, if you want to spend your money only once at chlorine tablets, I would recommend you to add them at night.

How to calculate Chorine Demand of your Pool?

Some people complain to me that their pool water has turned cloudy after chlorination. Their concern is genuine, as, after spending money, they still haven’t got the desired result. The basic reason why their pool water misbehaves is the chlorine demand. As the name suggests, “chlorine demand” is the amount of chlorine which your pool needs.

Add less, and the bacteria won’t be killed. Add more, and the pool water will turn cloudy. Therefore, if you want to save your money, calculate the chlorine demand of your pool. Manual methods are available, too, but I would recommend you to go digital.

After answering your queries regarding chlorination, let’s take a look at what are the best chlorine tablets for the swimming pool.
