Application
Swimming Pools & Spas (Outdoor): The primary application is to stabilize free chlorine in outdoor recreational water, preventing UV loss which can be as high as 90% in just a few hours.
Chlorinated Isocyanurates Production: It is the key raw material for manufacturing Trichloroisocyanuric Acid (TCCA) and Sodium Dichloroisocyanurate (SDIC).
Intermediate in Chemical Synthesis: Used in the production of herbicides, plastics, and flame retardants.
Swimming Pools & Spas: The primary choice for continuous disinfection, algae prevention, and water clarification.
Regular packing
Powder/Granules: 25 kg or 50 kg plastic woven bags, with a sealed inner plastic liner to prevent moisture absorption.
Customized Package
- 1.Retail Sizes: 1 lb, 2 lb, 4 lb, or 5 kg plastic bottles or buckets for the consumer market.
- 2.Bulk Sizes: 1000 kg jumbo bags (FIBCs) for large-volume users.
- 3.Private Labeling: Custom packaging with your brand name and design.
How to use
-
1
Test First Use a test strip or liquid test kit to determine the current Cyanuric Acid level in your pool. The ideal range is 30 - 50 ppm.
-
2
Calculate Dosage Based on your pool volume and current CYA level, calculate the amount needed to reach the ideal range. (e.g., approximately 1.5 lbs per 10,000 gallons to raise CYA by 10 ppm).
-
3
ApplicationBest Method: Add the pre-measured Cyanuric Acid to a clean sock or cloth bag. Suspend the bag in front of an active return jet in the deep end of the pool. Squeeze the bag periodically until all the powder has dissolved. This may take 24-48 hours.Alternative Method: You can pre-dissolve it in a bucket of warm water and pour it slowly into the skimmer. (Note: This method is not recommended for cartridge filters as it can cause clogging).

FAQ
Q1: Is Cyanuric Acid the same as chlorine?
A1: No. Cyanuric Acid itself is not a disinfectant. It is a stabilizer that protects chlorine from the sun. You must still use a chlorine source (like TCCA, SDIC, or liquid chlorine) to sanitize the water.
Q2: Can the Cyanuric Acid level get too high?
A2: Yes. This is a critical point. If CYA levels exceed 100 ppm, it can over-stabilize the chlorine, making it less effective at killing bacteria and algae. This is known as "Chlorine Lock." The only way to reduce high CYA is by partially draining and refilling the pool with fresh water.
Q3: Why is it so slow to dissolve?
A3: Cyanuric Acid has a naturally low solubility in water. This is why the "sock method" is recommended—it allows for slow, controlled dissolution and prevents undissolved powder from settling on the pool floor or clogging the filter.
Q4: Do I need to use Cyanuric Acid in an indoor pool?
A4: Generally, no. Since indoor pools are not exposed to direct sunlight, the primary cause of chlorine loss (UV rays) is absent. Using CYA in an indoor pool is unnecessary and can lead to over-stabilization.
Q5: Does Cyanuric Acid affect the pool's pH?
A5: Cyanuric Acid itself is mildly acidic. When added in large doses, it may cause a slight, temporary drop in pH. It is always good practice to test and adjust your pH and alkalinity after adding any chemical to your pool.
