How Does The Chlorine Tablet Works?

Chlorine is considered the best chemical for killing the viruses, algae, and bacteria present in your pool. When it comes in contact with these microorganisms, then it breaks down into chemicals such as hypochlorous acid that kills them by targeting the cells which create the microorganisms.

Why Should You Choose Chlorine Tablet Instead Of Liquid?

Most pool owners choose chlorine tablets instead of liquid or granular because instead of measuring, you only need to be aware of the size and drop the tablet. Also, tablets are considered pretty safe to use.

What All Things To Look For In A Chlorine Tablet?

There are specific things that you need to look for in a chlorine tablet.

Tablet size- A chlorine tablet comes in two sizes, one inch and three inches. It depends upon your pool size which tablet you should use.

Composition- Chlorine tablets consist of different chemicals. However, the important thing to ensure is that it should contain 90 percent chlorine.

Dissolve speed- The rate at which chlorine tablet dissolves is also important. If it dissolves too fast, your pool will be filled with chlorine, and if it dissolves too low, your pool will not have enough chlorine. Typically, your chlorine tablet should take seven to ten days to dissolve.
