Pool Shock Treatments

Pool Shock Treatments for weekly boost and problem solving your water.

Pools have the potential to become host to a plague of algae, bacteria, unwanted impurities and organic life matter. Pool shock products are used to sanitise the water, helping to keep it clean and safe for bathers. During this process, sanitiser 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 the pool shock treatments come in.

Shock treatments work by applying a dose of high strength chlorine once a week or as and when a boost in sanitisation is required. This causes the chlorine levels to quickly become effective.

It is wise to apply chlorine shock doses to a pool in the end of the day so that chlorine can work unhindered by sunlight. It is also advised to apply chlorine shock after heavy rain, if your pool has had a lot of use, and especially when you first spot signs of algae creeping in. Chlorine shock is also sometimes a useful fix for dealing with cloudy water. Applying pool chlorine shock should become a part of your regular pool maintenance checklist.

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.

Why Pool Shock? Can't I just use regular chlorine? 

Fun fact. Your standard chlorine is "stabilised", meaning it is designed to hang around and be present for a longer period of time. Pool shock chlorine is "non-stabilised", meaning it's designed to be used at a higher dose as it will burn off and return to safe levels much faster. This makes it ideal as a problem solver in your pool. If you did the same thing with your regular chlorine, it would take much longer after super-dosing before test strips indicate that it is safe again to use the pool!
