Why You Need to Shock Your Hot Tub

Between all the chlorine or bromine (even salt) we use to sanitize our spas and then balance the water with more chemicals, spa users often ask why they have to shock?

Sanitizers such as chlorine and bromine take care of killing bacteria, but over time as the spa gets used, dead waste builds up in the tub, including dead skin, natural oils and dirt. The cartridge filter does collect a great deal of it, but extra contaminants like cosmetics, body lotions, shampoos, laundry detergents and other personal care products can build up quickly, overwhelming the filters and cause the water to look less than desirable. These products are especially taxing on the sanitizer causing them to get depleted prematurely and this can also contribute to cloudy water and nasty odours.

Using a shock basically  goes to work on attacking and removing waste build up quickly so that the water quality is in peak condition and allows the sanitizer to do its job of killing bacteria.

There are many different ways to “shock” or “oxidize” a tub. One can use a liquid or granular chlorine or bromine, but must be used in higher doses to achieve oxidization. A great alternative is a “Non-chlorinated oxidizer” such as SpaGuard’s “Spa Lite” which does not contain any actual chlorine or bromine but performs as a booster to regenerate bromine and eliminate waste.

We recommend using an oxidizing shock such as SpaGuard’s “Spa Lite” on a weekly basis or as needed. This simple-to-use envelope is a pre-measured, blended shock that contains a water clarifier and does an amazing job of destroying all waste build up, restoring water sparkle and ridding the tub of bad odours.

Just be sure to leave your spa cover off for at least the length of a jet cycle (20-30 minutes) to ensure the underside of your cover is not damaged and wait at least the same amount of time before entering the spa.

Spa care has never been this easy, but the key is regular routine shocking as a preventative rather than waiting till the water takes a bad turn and having to be reactive.
