WATER CHEMISTRY
The effects of low PH can 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 Di-
chlor) 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 dis-
solved 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 Ozon-
ator, 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 sani-
tizer 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 intro-
duced 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 en-
velops materials in the water, commonly hardness ions, a sequestering
chemical prevents the ions from reacting with one another, thus forming
complex structures or solids.
12 - Shocking : Shocking is the act of hyper-chlorinating or hyper-oxidiz-
ing the water. This can be accomplished with a myriad of shock treat-
ments, 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, min-
eral 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.
