Sodium Dichlor shock is much easier to use and dissolve in a longer time than Calcium hypochlorite. The actual name of this is quite long as sodium dichloro-s-triazinetrione or dichloroisocyanuric acid.
- Most chlorine products, including Sodium Dichlor, contains 35% chlorine.
- Depending on the brand’s instruction, you may add it with water to dissolve before some time ahead of pouring to pool or directly add to the water.
