Wizard Granular Shock Chlorine 1KG
Pools and spas have the potential to become host to a plague of algae, and other bacteria, unwanted impurities and organic life matter. Chlorine is used to sanitise the water, helping to keep it clean and safe for bathers. During this process, chlorine levels can be broken down by the sunlight, combine with the impurities and deteriorate, reducing the ‘free’ chlorine level that it actively available to continue to sanitise the water. This is where shock comes in.
WARNING: Chlorine levels after a shock dosing (sometimes called ‘super-chlorination’) are extremely high and as such bathing should not be allowed until the chlorine has returned to safe levels, as indicated on your test strips. After any dosing of any chemicals, please always test prior to bathing.
