Quality Chlorine Tablets For Sanitizing Your Pool

Chlorine pucks stacked up into a total of 3 on edge of pool.

Sanitizing your swimming pools water is one of the most important things to keep your water clear all season long. One of the easiest and most used methods is chlorine tablets.

It is also worth mentioning that not all of them are equal. Some brands and manufactures have less available chlorine than others. With these products it will require more tablets to get the same levels of chlorine and while you may spend less, you will have to purchase additional tablets more frequently.


There are a few things you want to look for when it comes to picking your chlorine pucks for the season. It is also a good practice to order a large quantity prior to or just at the beginning of the season to save money and not need to worry about running out for quite some time.

  • Available chlorine should be at least 90%. You can purchase chlorine with as little as 70 to 80% available chlorine. These products have added fillers that are not needed, typically dissolve much quicker and will not keep your pool sanitized at the same standards.
  • Individually wrapped tablets are also a plus. This isn’t a complete deal breaker, but I prefer getting tablets that are each wrapped in the container. This helps prevent moisture from getting to the tables and keeps them fresher.
  • Contains Trichloro-S-Triazinetrione. If you see this as one of the ingredients, you are likely getting a high quality chlorine. This also adds Cyranuric Acid to the water gradually during use which helps the chlorine stay in the pool longer during the summer months.
  • Perfect size for inline, offline and floating chlorinators. I always recommend 3 inch size round tablets. These are the perfect size for just about any type of chlorinator you are using.

I usually purchase a 50 pound bucket of these for my pool at the beginning of each season. Sometimes I might even have a few tablets left over from the year before.

Even if it is mid season and you do not need such a large amount, you can choose from smaller quantities as well. If you are in need of replenishing your chlorine supply, you can do so by purchasing these In The Swim 3 Inch Chlorine Tablets. Choose the size that meets your needs.
