Nissan D.C.C.Na 60GI Sodium Dichloroisocyanuric Acid (SDIC) in 50kg drum

Sodium Dichloroisocyanuric Acid (SDIC for short) is another form of stablised chlorine. It has 60% chlorine availability and is best used for shock treatments (also known as super-chlorination) of swimming pools due to its quick release of chlorine. In other industries, it is often used as a bleaching agent.

The ICA ingredient in SDIC is what “stabilises” the chlorine: i.e., prevents the break down of chlorine due to UV rays from the sun. This aids to prolong the lifespan and sanitisation effect of chlorine in the pool, which is especially important in sunny countries like Singapore and/or when the pool is outdoors.

Nissan Chemicals is a leading manufacturer known for their high-quality chemicals worldwide. Pool Connect is proud to be their official distributor for the Singapore market.

* Daily dosage to be taken only as a reference. With the above amount, a pool volume of 300 m3 needs a daily dose 1.2 kg of Nissan D.C.C.Na 60GI. Actual dosage amount depends on the pool size, turnover rate, and weather conditions. Always ensure the parameters in the next table below are met after each dosage and at the end of the day.

Free Chlorine (Residual)+ 1.0 to 3.0 mg/L
pH Range+ 7.2 to 7.8
Cyanurate+ < 100 mg/L++
Total Alkalinity 80 to 100 mg/L
Copper+ < 0.2 mg/L

+ Indicates by law.
++ Caution is to be taken not to exceed this amount as too much cyanuric acid disables the sanitisation effects of chlorine. As cyanuric acid is a component of ICA, excessive use of SDIC might lead to this.

Note: 1 mg/L = 0.001 g/L = 1 g/m3 = 1 ppm
