Chlorinating Agents

Find your information about pool chemicals here:

Chlorinating agents are of two types: organic and inorganic. They are not compatible with each other and should never be used in combination. The same scoop or pail should not be used for both without thorough cleaning. One type should not be added after the other type in the pool chlorinator.

Inorganic chlorinating agents include calcium hypochlorite, sodium hypochlorite, and lithium hypochlorite. Organic chlorinating agents include potassium dichloroisocyanurate, trichloroisocyanuric acid, and sodium dichlorocyanurate (in anhydrous or dihydrate forms).
