Champion Granular Shock 65% Top Tip: - As soon as possible after a thunderstorm shock dose your pool with a 5mg/l dose of Champion Granular Shock Granules or Shock n Floc Granules. - The reason for this is that lightening creates nitrogen in the atmosphere and the rain washes this nitrogen into your pool. Nitrogen is plant food and algae thrive on it, so pool water can quickly turn green after a thunderstorm, a shock dose of chlorine can help prevent this. | | | --- | | 65% Shock Chlorine Granules D
