⚠ Important
- Use safety gloves and safety mask to protect skin and eyes from contact with this product.
- Never add sodium dichloroisocyanurate granules when the pool is being used, and always wait at least 30 minutes after adding.
- The pool water should be chlorinated at a level of 1.0 to 3.0 ppm while the pH should be kept in the range of 7.2 to 7.6.
Directions for Use
- Fill a plastic bucket with pool water. Add the correct weight of SDIC granules to the bucket, stir gently to mix thoroughly.
- Slowly pour the solution into the pool immediately above the pool return inlet whilst the pool circulation system is running.
- Keep the pool circulation system running for at least 30 min after adding.
- Test the pool water to ensure that the required chlorine concentration of 1.0 to 3.0 ppm has been established.
General Precautions
- Ensure that the filter and the pool circulation system work well.
- Always handle products in a well-ventilated area.
- Always wash hands thoroughly after handling pool chemicals.

Frequently Asked Questions
QWhat is Sodium Dichloroisocyanurate (SDIC) and how does it work?
Sodium Dichloroisocyanurate (SDIC) is a chlorine-based disinfectant and biocide. When dissolved in water, it releases active chlorine, which acts as a powerful oxidizing agent to eliminate bacteria, viruses, fungi, and algae across a wide range of applications.
QWhat is the difference between SDIC Dihydrate Granules and SDIC Granules?
SDIC Dihydrate Granules (CAS 51580-86-0) contain water of crystallization and have an available chlorine content of 55–56% MIN. SDIC Granules (CAS 2893-78-9) are anhydrous and offer a higher available chlorine content of 60% MIN, making them more concentrated.
QWhat is the recommended chlorine level and pH range for swimming pools using SDIC?
The pool water should be maintained at a chlorine concentration of 1.0 to 3.0 ppm. The pH level should be kept within the range of 7.2 to 7.6 to ensure effective disinfection and swimmer safety.
QWhat certifications does SDIC hold and what industries does it serve?
SDIC granules are certified under NSF, REACH, and BPR standards. They are suitable for water treatment, food processing, agriculture, public health facilities, household disinfection, and the textile industry.
QHow should SDIC granules be stored safely?
SDIC granules should be stored in a dry, cool, and well-ventilated area away from direct light, heat, and ignition sources. Keep containers tightly sealed after use and store away from strong reducing agents, strong acids, or water. Always keep out of reach of children.
QWhat packaging options are available for SDIC granules?
SDIC granules are available in HDPE drums, fiber drums, and plastic pails in sizes of 1 kg, 5 kg, 10 kg, and 50 kg. For bulk orders, jumbo bags and customized packaging options are available to meet specific client requirements.
