The colors and shapes of TCCA tablets are not just for looks. Each type—from simple white tablet to double layer tablet or white tablet with blue dot ones—is designed for a specific use, helping keep different kinds of water clean and safe.
1 Evolution: From Single to Multiple Forms
The type of TCCA has evolved far beyond the standard white tablet. What began with the safety-driven blue tablet has grown into a full spectrum of specialized solutions, each designed to make water care safer, simpler, and more effective for every user and every type of pool.
2 Core Differences: More Than Just Color
Think of TCCA tablets like tools in a toolbox—the core material is strong, but each tool has a special job. The color tells you what that job is: fast action, long-lasting protection, or easy monitoring.
Check the table to pick the right tool for your water.
Tablet Type | Appearance | Core Efficacy and Features |
White Tablet |
| A cost-effective disinfectant tablet with strong chlorine power (≥90%) and steady release. |
Blue Tablet |
| A safe, visible disinfectant. Just as effective as white tablets, the added blue color makes it easy to spot in water and helps prevent accidents. |
Double Layer Tablet |
| The white layer dissolves quickly to rapidly increase chlorine concentration, while the blue layer provides slow-release and long-lasting stability, reducing chlorine value fluctuations. |
Blue Dot in the Middle White Tablet |
| Each tablet dissolves slowly, and a single application can maintain disinfection for a long time, greatly reducing the frequency of management. |
White Tablet with Blue Dot |
| The efficacy is same as white tablets,but blue dots can serve as a "dissolving progress bar", indicating when the tablets are almost used up. |
