Introduction

Trichloroisocyanuric Acid (TCCA) tablets, also known as trichlor tablets, feature slow and steady dissolution with long-lasting active chlorine release. They provide powerful, broad-spectrum disinfection and algae control, effectively maintaining clean, clear and safe water in swimming pools, water landscapes and aquaculture systems. Highly stable and easy to use with the dosers, they ensure consistent water quality and convenient long-term management.

Chemical Properties
Chemical Name Trichloro-s-triazinetrione
Appearance Tablets
Hazard Class/Division 5.1
Specification 200g
Advantage Effective in killing bacteria and lasting for a long time
Core Features & Performance

Unlike regular TCCA tablets, these tablets release active chlorine fast and keep disinfecting for much longer. This slow-release property eliminates frequent manual dosing, reducing labor costs and ensuring continuous, uninterrupted disinfection. The tablets feature excellent storage stability, retaining their effectiveness for an extended shelf life when stored in cool, dry conditions.

Fast & Long-Lasting Release
Rapid initial chlorine release followed by sustained disinfection action over extended periods.
🔧 Reduced Labor Costs
Slow-release design eliminates the need for frequent manual dosing and monitoring.
📦 Excellent Storage Stability
Retains full effectiveness when stored in cool, dry conditions for extended shelf life.
Advantages

Compared with ordinary disinfectants, TCCA tablets have significant advantages: their high available chlorine content ensures excellent disinfection effect, the slow-release design reduces the frequency of application, and the stable performance can maintain the stability of water quality. It is convenient to use, cost-effective and environmentally friendly.

The product is chemically stable in a dry state. When stored in a sealed container at room temperature for two years, the loss of available chlorine is minimal, and there will be no volatilization or caking phenomenon. Compared with liquids and powders, as solid tablets, they are less likely to leak and produce dust. For anyone seeking high-performance, low-maintenance cost commercial or industrial water disinfection products, they are ideal choices.

Application
  • 1 Commercial & Residential Swimming Pools: Provides continuous sanitation for high-traffic water features, ensuring the elimination of bacteria and viruses.
  • 2 Industrial Cooling Towers: Prevents the growth of biological slime and algae in cooling systems, improving heat exchange efficiency.
  • 3 Aquaculture & Fish Farming: Effectively disinfects pond water and equipment, preventing the spread of bacterial diseases like Vibrio in shrimp and fish stocks.
  • 4 Textile & Paper Industry: Acts as a high-efficiency bleaching agent for fibers and pulp, providing excellent whiteness with controlled fiber damage.
Usage Notes
  • ⚠️ Store in a cool, dry, well-ventilated area, away from sources of fire, heat, acidic substances, and organic materials. Do not store together with other disinfectants.
  • 🧤 Wear gloves and safety goggles during use. Avoid direct contact with skin and eyes.
  • 🏊 When using in swimming pools, it is recommended to use a dosing device; do not apply directly to pool liners or fiberglass surfaces to prevent corrosion or discoloration caused by excessive local concentration.
  • 🔬 Regularly monitor the water's pH level and residual chlorine content. Trichlor tablets may slightly lower the pH; add a pH adjuster as needed to maintain water quality balance.
  • 📏 Strictly adhere to the standard dosage to avoid overuse, which can lead to the accumulation of cyanuric acid and impair disinfection effectiveness.
Frequently Asked Questions
Q What is the available chlorine content in TCCA 200g tablets?
TCCA (Trichloroisocyanuric Acid) tablets typically contain approximately 90% available chlorine, which is significantly higher than many other chlorine-based disinfectants. This high concentration ensures powerful and effective disinfection even at lower dosage rates.
Q How often should TCCA trichlor tablets be added to a swimming pool?
Thanks to their slow-release design, TCCA 200g trichlor tablets typically need to be replenished every 5–7 days depending on pool volume, bather load, and weather conditions. Using a floating doser or automatic feeder helps maintain consistent chlorine levels with minimal manual intervention.
Q Can TCCA tablets be used in fiberglass or vinyl-lined pools?
TCCA tablets should never be placed directly on fiberglass or vinyl pool surfaces, as the concentrated chlorine can cause bleaching, staining, or surface damage. Always use a floating dispenser or in-line feeder to ensure even distribution and prevent direct contact with pool surfaces.
Q What is cyanuric acid buildup, and how can it be managed?
Cyanuric acid (CYA) is a stabilizer naturally released as TCCA dissolves. Over time, CYA can accumulate in pool water and reduce chlorine effectiveness — a phenomenon known as "chlorine lock." To manage this, regularly test CYA levels and keep them between 30–50 ppm. If levels exceed 80 ppm, partial water replacement is recommended to dilute the concentration.
Q How should TCCA tablets be stored to maintain their effectiveness?
TCCA tablets should be stored in a cool, dry, and well-ventilated location away from heat sources, flames, acids, and organic materials. When kept in a sealed container at room temperature, the product can maintain its available chlorine content with minimal loss for up to two years, without caking or volatilization.
Q Are TCCA tablets safe for use in aquaculture and fish farming?
Yes, TCCA tablets are widely used in aquaculture to disinfect pond water and farming equipment, helping to prevent bacterial diseases such as Vibrio infections in shrimp and fish. However, it is essential to follow recommended dosage guidelines carefully, as excessive chlorine levels can be harmful to aquatic life. Always allow residual chlorine to dissipate to safe levels before introducing fish or shrimp.
