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.

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.

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
  • 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 (FAQ)
What is Trichloroisocyanuric Acid (TCCA) and how does it work?
TCCA is a chlorine-based disinfectant that slowly dissolves in water, continuously releasing active chlorine (hypochlorous acid). This kills bacteria, viruses, algae, and other pathogens, keeping pool or aquaculture water clean and safe over an extended period.
How long do TCCA 200g tablets last in a swimming pool?
The slow-release formulation of TCCA 200g tablets allows them to provide continuous disinfection for several days, depending on water volume, temperature, bather load, and sunlight exposure. Using a floating dispenser or feeder helps regulate the dissolution rate for optimal longevity.
Can TCCA tablets lower the pH of pool water?
Yes, trichlor tablets are slightly acidic and may gradually lower the pool's pH over time. It is recommended to regularly test pH levels and add a pH increaser (such as sodium carbonate) as needed to maintain a balanced range of 7.2–7.6 for safe and effective disinfection.
Are TCCA tablets safe to use in aquaculture and fish farming?
Yes, when used at the correct dosage, TCCA tablets effectively disinfect pond water and equipment without harming fish or shrimp stocks. They help prevent bacterial diseases such as Vibrio. Always follow recommended dosing guidelines and allow chlorine levels to dissipate to safe levels before restocking.
What is the shelf life of TCCA tablets and how should they be stored?
TCCA tablets are highly stable in dry conditions. When stored in a sealed container in a cool, dry, and well-ventilated area at room temperature, they retain their available chlorine content for up to two years with minimal loss. Avoid exposure to heat, moisture, acidic substances, and organic materials.
What happens if too many TCCA tablets are used?
Overuse of TCCA tablets can lead to an accumulation of cyanuric acid (CYA) in the water. Excessively high CYA levels can reduce the effectiveness of chlorine disinfection, a phenomenon known as "chlorine lock." It is important to monitor CYA levels and adhere to the recommended dosage to maintain effective water treatment.
