Guidance for Use in Swimming Pools

Sodium dichloroisocyanurate is the best choice of quickly raising the chlorine level or daily disinfection of swimming pools and spas. It is quickly dissolved and will not damage liner.

Important

  • Use safety gloves and safety mask to protect skins and eyes from contacting with this product.
  • 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 kept in the range of 7.2 to 7.6.

Directions for Use

  1. Fill a plastic bucket with pool water. Add the correct weight of SDIC granules to the bucket, stir gently to mix thoroughly.
  2. Slowly pour the solution into the pool immediately above the pool return inlet whilst the pool circulation system is running.
  3. Keep the pool circulation system running for at least 30 min after added.
  4. 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.

⚠️ Caution

  • Keep in a dry, cool and ventilated place away from light.
  • Keep out of reach of children.
  • Keep away from heat and sources of ignition.
  • Keep the container cap closed tightly after use.
  • Store away from strong reducing agents, strong acids or water.

🚨 Safety

  • Minimize contact.
  • NEVER MIX WITH ANY OTHER PRODUCTS.
Frequently Asked Questions
Q What is Sodium Dichloroisocyanurate (SDIC) and how does it work?
Sodium Dichloroisocyanurate (SDIC) is a chlorine-releasing disinfectant and biocide. When dissolved in water, it releases active chlorine, which acts as a powerful oxidizing agent to eliminate bacteria, viruses, fungi, algae, and other harmful pathogens across a broad spectrum.
Q What is the difference between SDIC Granules and SDIC Dihydrate Granules?
The main difference lies in their available chlorine content and molecular formula. SDIC Granules contain at least 60% available chlorine (CAS No. 2893-78-9), while SDIC Dihydrate Granules contain 55%–56% available chlorine (CAS No. 51580-86-0) due to the presence of two water molecules in their structure.
Q What is the recommended chlorine level and pH range for swimming pool treatment?
The pool water should be maintained at a chlorine concentration of 1.0 to 3.0 ppm. The pH should be kept within the range of 7.2 to 7.6 to ensure effective disinfection and swimmer safety.
Q What certifications does SDIC hold, and is it safe for use in drinking water and pools?
SDIC granules are certified under NSF, REACH, and BPR standards, confirming their safety and suitability for use in drinking water treatment, swimming pools, and various industrial and public health applications when used as directed.
Q How 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 sources of ignition. They must be kept away from strong reducing agents, strong acids, and water. Always keep containers tightly sealed and out of reach of children.
Q What 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, they can be supplied in jumbo bags or customized packaging tailored to specific client requirements.
