Description
Waterwell Sudden Shock is a powerful pool oxidiser formulated with Sodium Dichloroisocyanurate to deliver fast, effective shock treatment results in swimming pools. Designed to oxidise and eliminate organic contaminants such as body oils, sweat, sunscreen, and other debris that accumulate through regular pool use, Sudden Shock restores water clarity, eliminates unpleasant odours, and reactivates the sanitizing efficiency of chlorine in a single application. Its dual-action formula simultaneously controls algae and kills harmful bacteria, making it a comprehensive shock treatment that addresses multiple water quality issues at once. The stabilised sodium dichloroisocyanurate base also contributes active chlorine back into the pool water during treatment, extending its sanitizing effect beyond the initial oxidation. Packaged in a convenient 500g resealable pouch for easy dosing and application, Waterwell Sudden Shock is a reliable and versatile pool shock treatment for residential pool owners who need fast, effective water restoration after heavy use, algae outbreaks, or periods of poor water quality.
