be rapid sanitizer loss, eye and skin irritation, expedited corrosion of

metals, as well as staining throughout the spa. High PH can result in

cloudy water, low sanitizer efﬁciency, as well as eye and skin irritation.

3 - Parts per Million (PPM): The term “parts per 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 preferred 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.

9 - Organic Matter: These are carbon-derived substances typically

generated by living organisms. In a spa, they are most frequently

introduced into the water by bathers. Enzyme products such as Spa

Perfect by Natural Chemistry are most effective at eliminating organic

matter from your body of water.

10 - Microorganisms: This term refers to tiny, living organisms such

as bacteria, protozoa, or algae.

11 - Sequestering: This term deﬁnes the action taken to remedy high

levels of metals or calcium in the water. By forming a complex that

envelops materials in the water, commonly hardness ions, a

sequestering chemical prevents the ions from reacting to one another,

thus forming complex structures or solids.

12 - Shocking: Shocking is the act of hyper-chlorinating or

hyper-oxidizing the water. This can be accomplished with a myriad of

shock treatments, but is most commonly accomplished with Sodium

Dichlor or Potassium Monopersulfate. The former raises the

sanitizer level to at least 8 PPM, and the latter burns off chloramines

or bromines. The use of P.S., or non-chlorine shock is advantageous

because you can bathe only 15 minutes after treatment; however,

oxidizing the water will not kill the bacteria unless there is sufﬁcient

total chlorine to free up used chlorine to actively sanitize.

13 - Bather Load: You may be asked by your spa professional what

the average bather load is, meaning, how many people enter the spa

on a daily or weekly basis.

14 - Alternative Sanitizers: A group of products that sanitize pool,

spa and hot tub water, by means other than the application of

chemicals to the water. Includes such products as ultraviolet sanitizing

systems, mineral puriﬁers, ionizers and ozonators.

15 - Bactericide: A chemical that kills bacteria. The most common

bactericides are: chlorine, bromine, biguanide, ozone and silver. Most

algaecides, other than copper, exhibit some bactericidal properties.

16 - Balanced Water: Pool or spa water that is within the accepted

water analysis parameters for: pH, sanitizer, total alkalinity, calcium

hardness, chlorine stabilizer (chlorine pools only) and minerals. The

balancing of the pool or spa water helps to eliminate water chemistry

problems.
