Trichlor, scientifically known as Trichloro-S-Triazinetrione or Trichloroisocyanuric acid, is a highly concentrated form of chlorine. They are most commonly found as 1″ to 3″ tablets.

Whenever you hear pool owners or pool store associates refer to "tabs," "tablets," or "pucks," they are usually referring to trichlor.

Advantages of Trichloroisocyanuric Acid

● At 90% concentration, trichlor is easily the most effective and best "bang for your buck" when it comes to sanitation. You will also need less of it when compared to liquid chlorine or cal hypo.

● Because it is so popular, pretty much any pool store and big box store will have tablets available.

● It has a very long shelf-life compared to other forms of chlorine. Rarely will it lose its overall strength over time.

● It is super convenient and easy to work with. Just put the recommended amount of tabs in a dispenser or chlorinator and that is all there is to it.
