When it comes to pool maintenance, choosing the suitable disinfection method is essential. TCCA 90 chlorine tablets, as excellent swimming pool chemicals, are often the first choice for managers of big pools. But for those green hands in swimming pool maintenance, they might wonder, is TCCA 90 the same as chlorine? The short answer is No. Why not the same? This article can help a lot.
What Is TCCA 90?

TCCA 90, the full name is trichloroisocyanuric acid, a powerful pool disinfectant containing 90% available chlorine content. TCCA 90 is available in three forms: granules, powder and tablets. Among them, tablets are the most commonly used. TCCA 90 chlorine tablets are usually available in the form of 200g or 20g. If you want other specifications, we can provide customization services.
TCCA 90 chlorine tablets are slow-dissolving disinfectants. This slow dissolution form makes TCCA 90 particularly convenient for pool maintenance - you can simply place the tablets in feeders or floaters, and over time, they will release disinfecting properties.
What Is Chlorine?

Chlorine itself refers to the active element form (Cl2) or compounds (such as bleaching water or calcium hypochlorite) used for disinfection. All these forms will release active chlorine (usually in the form of hypochlorous acid) into the water, thereby killing viruses, bacteria and other microorganisms. Put simply, chlorine can generally refer to a certain category, and TCCA 90 chlorine tablets are a type of chlorine disinfectant.
Although pure liquid or gaseous chlorine is often used for large-scale water treatment facilities, TCCA 90 provides pool managers with a convenient method to achieve controllable and continuous direct release of chlorine into the swimming pool. Moreover, compared with bleaching water, TCCA 90 is not only convenient to store but also has a longer shelf life.
TCCA 90 vs. Chlorine - Are they the same?
Not exactly the same. As mentioned above, TCCA 90 is a type of chlorine disinfectant. TCCA 90 is stabilized chlorine, containing cyanuric acid, which helps protect chlorine from UV rays and prevent the loss of free chlorine under strong sunlight. Therefore, TCCA 90 chlorine tablets are particularly suitable for outdoor swimming pools.
