Swimming Pool Shock Treatments

Swimming Pool Shock & Sanitiser products are made from calcium hypochlorite and contain no stabiliser, which when present in excess, may inhibit chlorine activity. Superfast Granules dissolve rapidly when added to swimming pool water and produce an impressive 78% available chlorine.

Ideal for indoor and outdoor swimming pools, with both granular and tablet versions helping to balance the water in soft water areas
