- Never add sodium dichloroisocyanurate granules when the pool is being used, and always wait at least 30 minutes after added.
- The pool water should be chlorinated at a level of 1.0 to 3.0 ppm while the pH should be keep 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 added.
- Test the pool water to ensure that the required chlorine concentration of 1.0 to 3.0 ppm has been established.

Frequently Asked Questions
What 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 broad spectrum of applications.
What is the difference between SDIC Dihydrate Granules and SDIC Granules?
SDIC Dihydrate Granules contain water of crystallization (2H₂O) and typically offer 55–56% available chlorine, while standard SDIC Granules are anhydrous and provide a higher available chlorine content of 60% minimum. They have different CAS numbers: 51580-86-0 and 2893-78-9 respectively.
What is the recommended chlorine level and pH range for swimming pools using SDIC?
The pool water should be maintained at a chlorine level of 1.0 to 3.0 ppm. The pH should be kept within the range of 7.2 to 7.6 for optimal disinfection efficacy and swimmer comfort.
Can SDIC granules be used in industries other than swimming pools?
Yes. SDIC granules are versatile and widely used across water treatment, food processing, agriculture, public health facilities, household disinfection, and the textile industry for bleaching purposes.
What certifications do these SDIC granules hold?
Our SDIC granules are certified under NSF (National Sanitation Foundation), REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals), and BPR (Biocidal Products Regulation), ensuring compliance with international safety and quality standards.
How should SDIC granules be stored safely?
SDIC granules should be stored in a dry, cool, and well-ventilated place away from direct light, heat sources, and ignition. Keep containers tightly sealed after use and store away from strong reducing agents, strong acids, or water. Always keep out of reach of children and never mix with other chemical products.
