Owning a pool in a backyard means that you will spend much time to keep the water clean. To keep it clean, you need to add a sanitizer. One of the most popular sanitizer for pool water is chlorine. Chlorine is available in three forms: granules, liquids, and tablets. Liquid and granules are the easiest form of chlorine as you just need to directly apply it to the pool water. While you just need to directly apply liquid and granules, you will need an extra effort if you decide to use chlorine tablets.

If you add chlorine tablets in the pool, it will make a big difference. You may wonder why chorine tablets are better than other forms of chlorine such as liquid and granule. Well, chlorine tablets are easier to use, and they dish out chlorine at a steadier rate than mixing a few scoops of granules to the pool water.

Maintaining a pool may seem so easy-peasy. But, you have to add chlorine in the right quantity to sanitize the pool water appropriately. There are two values that need to be checked to have a healthy pool. The pH value must be between 7.2 to 7.6.

To use the right amount of chlorine tablets, first of all, you need to determine the volume of your pool. Round the volume of your pool up to 5,000 gallons. For example, if your pool has 20,000 gallons of capacity, you’ll need to add 4 tablets.
