Waterwell Sudden Shock — 500g

Waterwell Sudden Shock is a chlorine-based pool shock treatment. Shock treating raises the chlorine level rapidly to burn off organic contaminants, kill algae, and break down chloramines (combined chlorine) that cause the “chlorine smell” and eye irritation. Shock your pool every 2 weeks in summer, weekly with heavy use, or after storms and heavy rain.

How to Use

Dissolve Sudden Shock in a bucket of pool water first, then pour around the pool edges with the pump running. Do not swim until chlorine levels return to 1–3 ppm (usually 24 hours).
