Chlorine tablets can be an excellent method of disinfection for use in water tanks and pools. But do chlorine tablets have a shelf life?
What are Chlorine Tablets?
Chlorine tablets are active disinfectants used in swimming pools, hot tubs, spas, and water tanks, among other types of applications. These tablets come in various shapes and sizes, and the amount of chlorine contained in each type can be different. Most chlorine tablets contain approximately 90% calcium hypochlorite and 10% inert binders. A unique feature of chlorine tablets from other disinfectants is that these tablets can slow-release chlorine, allowing for effective disinfection over a long period.
Do Chlorine Tablets Have a Shelf Life?
Chlorine tablets do have a shelf life, although this length of time may vary depending on the type and size of the tablet. Generally speaking, chlorine tablets are expected to last for one to two years before the amount of chlorine will begin to diminish. This means that it is important to store chlorine tablets correctly, in a cool and dry location, away from direct sunlight. It is also important to not mix different types or sizes of chlorine tablets, as they will all have different shelf-lives.
Tips for Maximizing Shelf Life
- Store in cool and dry locations – It is important to store the tablets in a location away from direct sunlight and heat, as this will help retain their active chlorine content.
- Regularly check chlorine content – It is important to check the chlorine content regularly to make sure it is still effective.
- Keep away from other sources of chlorine – Chlorine tablets should be stored as far away from other sources of chlorine as possible, such as cleaning supplies containing chlorine.
- Throw out expired tablets – Chlorine tablets should be thrown out after their expiration date, as their chemical properties may no longer be effective at disinfecting.
Chlorine tablets can be a great addition to any water tank or pool, providing effective disinfection over an extended period. However, it is important to remember that chlorine tablets have a shelf life and should be stored correctly in order to maximize the amount of time they will be effective. Additionally, regularly check the chlorine content of the tablets to guarantee that they are still effective.
