  • Features Highly effective in killing bacteria, slow dissolution, long-lasting efficacy

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 active chlorine release with prolonged disinfection duration
  • Slow-release design eliminates frequent manual dosing
  • Reduces labor costs and ensures continuous disinfection
  • Excellent storage stability in cool, dry conditions
  • Extended shelf life with minimal chlorine loss over time
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.

  • High available chlorine content for excellent disinfection performance
  • Chemically stable in dry state — no volatilization or caking after 2 years sealed storage
  • Minimal chlorine loss when stored at room temperature in sealed containers
  • Solid tablet form reduces risk of leakage and dust compared to liquids and powders
  • Ideal for high-performance, low-maintenance commercial or industrial water disinfection
  • Cost-effective and environmentally friendly long-term solution
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
  • 1 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.
  • 2 Wear gloves and safety goggles during use. Avoid direct contact with skin and eyes.
  • 3 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.
  • 4 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.
  • 5 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
QWhat is Trichloroisocyanuric Acid (TCCA) and how does it work?
ATCCA is a solid chlorine-releasing compound used for disinfection and water treatment. When dissolved in water, it releases hypochlorous acid, which effectively kills bacteria, viruses, algae, and other pathogens, maintaining safe and clean water quality.
QHow long do TCCA 200g tablets last in a swimming pool?
AThanks to their slow-release design, TCCA 200g tablets dissolve gradually, providing continuous disinfection over several days. The exact duration depends on water temperature, pool volume, bather load, and sunlight exposure, but they significantly reduce the need for frequent manual dosing compared to regular chlorine products.
QCan TCCA tablets be used in aquaculture and fish farming?
AYes. TCCA tablets are widely used in aquaculture to disinfect pond water and equipment, effectively preventing the spread of bacterial diseases such as Vibrio in shrimp and fish populations. Dosage must be carefully controlled to avoid harming aquatic life.
QWhat is the proper way to store TCCA tablets?
ATCCA tablets should be stored in a cool, dry, and well-ventilated area, away from heat sources, open flames, acidic substances, and organic materials. When kept in a sealed container at room temperature, the product retains its effectiveness for up to two years with minimal chlorine loss.
QDo TCCA tablets affect the pH level of pool water?
AYes, trichlor tablets have a low pH (around 2.8–3.0), which means regular use may gradually lower the pH of pool water. It is recommended to regularly monitor both pH and residual chlorine levels, and add a pH adjuster (such as soda ash) as needed to maintain the ideal balance of 7.2–7.6.
QWhat are the safety precautions when handling TCCA tablets?
AAlways wear protective gloves and safety goggles when handling TCCA tablets. Avoid direct skin and eye contact. Never mix TCCA with other disinfectants or chemicals. Use a dosing device when adding tablets to pools, and strictly follow the recommended dosage to prevent cyanuric acid buildup and reduced disinfection effectiveness.
