1. One reason for shocking your spa is to break-down organic waste contaminants which cause odour and cloudy water. Once treated with spa shock, water quality and clarity is usually completely restored.
2. Shocking your spa removes irritating chloramines by converting them back to active chlorine if you are using chlorine sanatisers. Chloramines are a combination of ammonia with chlorine which can cause skin, eye and respiratory irritation in some people.
3. Some people look at spa shock as a get-out-of-jail card to be used after a large bather load or if the spa water is not maintained correctly for a certain amount of time. Although not a fix-all, Spa Shock can bring spa water back to a higher level of clarity.
Spa Shocks are compatible with most sanitizing systems. We recommend a Chlorine free (MPS) spa shock which works well with chlorine and chlorine free sanatiser's. This shock is also compatible with Nature2 spa sticks and Simple Silver.
Warning:
If you have a Vortex or O2 spa and you are using Purezone Micron filters you should not use an MPS spa shock.
The MPS shock can react with the Purezone filter media and cause the Purezone micron filters to prematurely clog.
Instead of an MPS shock you will want to use a higher dose of Lithium sanitiser as a shock. Please follow the dosing instructions on the label of your Lithium sanitiser.
No matter your method of shocking, make sure to remove your spa cover for at least 45 minutes after adding the shock.
