Pool Care Guide: Shocking
Shocking the Pool Water (Super Chlorination)
To effectively eliminate chloramines from pool water, super chlorination or "shocking" is necessary. Shocking should be performed on a weekly basis or whenever you notice a "chlorine odour" . Shock your pool using either AQUA Shock or AQUA Brite Plus.
AQUA Shock is calcium hypochlorite or what we call unstabilized chlorine. The best time to use AQUA Shock is last thing in the evening because it will raise both your the pH and the chlorine residual. They will both return to normal after a few hours.
AQUA Brite Plus, on the other hand, is a non-chlorine shock and swimming can be permitted after a 15 minute waiting period. AQUA Brite Plus can be added directly into the pool and leaves no residual.
