Bargain price for 10kg worth of Sodium Dichlorisocyanuric - Spa and Pool stabilized pool chlorine.

Unlike liquid sodium hypochlorite, it is in a granular form, and is stable on a long term basis when kept in cool dry conditions in a closed container.

Because it does not contain calcium, it can be used to sanitise hard water without increasing the calcium hardness

It is reasonably close to neutral when dissolved in water and therefore requires less pH correction than trichlor and calcium or sodium hypochlorite

The use of stabilised chlorine granules (Dichlor) adds isocyanuric acid to the pool water which resists chlorine loss from the effects of bright sunlight

Please feel free to ask questions.
