What Are Stabilized 3-Inch Chlorine Tablets and How Do They Work?
Stabilized 3-inch chlorine tablets are a type of chlorine sanitizer used primarily in swimming pools and spas to maintain clean and safe water. They are called ‘stabilized’ because they contain cyanuric acid, which helps protect the chlorine from being degraded by sunlight. This stabilization allows the chlorine to last longer in outdoor pools, reducing the frequency of applications needed.
The tablets dissolve slowly, releasing chlorine over an extended period, which helps in maintaining a consistent level of sanitation in the water. Typically, these tablets are added to a floating dispenser or automatic chlorinator, ensuring a steady release of chlorine as the tablet dissolves.
Key features of stabilized 3-inch chlorine tablets include:
| Feature | Description |
|---|---|
| Effective sanitation | Maintains water clarity and sanitation |
| UV protection | Reduced chlorine loss from UV exposure due to cyanuric acid |
