3 - Parts per Million (PPM): The term “parts pre million” will be used

frequently in the world of water care. The term simply means

exactly what it says: the coexistence of any one unlike item with a

larger number of “like” items.

4 - Sanitizers: Sanitizers are used to destroy bacteria and other germs

in the water. Only 2 sanitizers are used in spas, chlorine (Sodium

Dichlor) and Bromine (Hydrotech or Lonza). Without the use of a

mineral system or an enzyme, the perferred level of sanitizer is

between 2 and 3 ppm.

5 - Total Dissolved Solids (TDS): TDS is simply the measure of the

total amount of matter dissolved in the water. When this level

becomes too high, action is advised.

6 - Calcium Hardness: The measure of the amount of calcium

dissolved in the water as expressed in PPM. Hard water, or water with

calcium levels over 250 PPM can cause scale formation on the

surface of the spa or the components of the spa.

7 - Total Chlorine: Total Chlorine is the sum of the free and combined

chlorines in the water. Often, water will contain a higher level of total

chlorine than available chlorine. If this is the case in your water, you

may use a non-chlorine shock (typically potassium monopersulfate) to

free up the remainder of total chlorine.

8 - Ozone: Ozone is a gas molecule that can be generated by an

Ozonator, which is composed of three atoms of oxygen and used to

oxidize the water. Ozone is very useful for regenerating bromine from

bromide ions. It also acts as a supplement when used in conjunction

with a sanitizer and may reduce the level of sanitizer required. You

may read more about ozone later in this section of your owner’s

manual.
