COMMON WATER CHEMISTRY QUESTIONS
Answer:
for three reasons:
the sanitizer level can be extremely high. High sanitizer levels
can chemically burn or discolor the spa's shell or the underside
of the cover. Then, after a period of time, the sanitizer level
level will allow viruses, bacteria or algae to grow.
2.Floaters tend to stay in one area of the spa most of the time,
causing this area to be exposed to extreme sanitizer levels.
of sanitizer will chemically burn (blister) the spa shell. Although
of spa chemicals, no spa surface can withstand this type of
highly concentrated chemical. Remember, chemical abuse is
Question: When I open my spa, I smell chlorine. How do I
Answer:
is the Free Available Chlorine, which is the chlorine available to
sanitize your spa. This free Available Chlorine does not have an
odor. The second is Chloramine, which is residue from chlorine
already expended. Chloramines have a strong chlorine odor.
The smell from Chloramines can be eliminated by "shocking" the
water. If you smell chlorine in the water, your spa is reminding
you to add a shock treatment.
Answer: Soft water is essentially the same as regular water
except that most or all of the calcium has been replaced by
sodium. Soft water may be corrosive to the heater and other
components. Replacement of spa components damaged by soft
water is extremely expensive.
Question: I am trying to reduce the number of chemicals to
Answer: While over-exposure to any chemical can be unhe-
In the case of spa water, the chemicals recommended in the
Spa Water Maintenance program are needed to protect the user
from water-borne pathogens (disease-causing microbes) and to
prevent corrosion of spa components.
Question: Why isn't water chemistry damage covered by
Answer: The chemical levels and water quality of the water in
the spa are under your direct control. With proper basic care, the
spa will provide many years of hot water relaxation. If you are
unsure about any chemical or its usage in the spa, contact your
Authorized Dealer or Manufacturer.
WATER TERMINOLOGY
to better understand the water maintenance process.
Bromamines: Compounds formed when bromine combines
loramines, bromamines have no pungent odor and are effective
sanitizers.
Bromine: A halogen sanitizer (in the same chemical family as
chlorine). Bromine is commonly used in stick, tablet, or granular
form. See the DO's and DON'Ts of Spa Water Maintenance for
additional information.
Calcium Hardness: The amount of dissolved calcium in the spa
water. This should be approximately 150-200 ppm. High levels
of calcium can cause cloudy water and scaling. Low levels can
cause harm to the spa equipment.
Chloramines: Compounds formed when chlorine combines with
nitrogen from body oils, urine, perspiration, etc. Chloramines
bromamines, chloramines are weaker, slower sanitizers.
Chlorine:
recommends the use of sodium dichlor-type granulated chlorine.
This type is preferred because it is totally soluble and nearly pH
neutral.
Chlorine (or Bromine) Residual: The amount of chlorine or
bromine remaining after chlorine or bromine demand has been
is chemically available to kill bacteria, viruses and algae.
Corrosion: The gradual wearing away of metal spa parts, usually
caused by chemical action. Generally, corrosion is caused by low
pH or by water with levels of TA, CH, pH or sanitizer which are
outside the recommended ranges. DPD: The preferred reagent
used in test kits to measure the Free Available Chlorine.
Halogen:
bromine, iodine, and astatine.
MPS: Monopersulfate is a non-chlorine oxidizer.
The use of an oxidizing chemical is to prevent the
combined chlorine and improve water clarity.
Pathogen: A microorganism such as bacterium that cause
disease.
pH: The measure of the spa water's acidity and alkalinity. The
recommended pH for the spa water is 7.4 to 7.6. Below 7.0
(considered neutral), the spa water is too acidic and can damage
the heating system. Above 7.8, the water is too alkaline and can
result in cloudy water, and scale formation on the shell and heater.
ppm: The abbreviation of "parts per million", the standard
measurement of chemical concentration in water. Identical to
mg/l (milligrams per liter).
Reagent: A chemical material in liquid, powder, or tablet form for
use in chemical testing.
Sanitizer: Sanitizers are added and maintained at recommended
residuals to protect bathers against pathogenic organisms which
can cause disease and infection in spa water.
Scale: Rough calcium-bearing deposits that can coat spa
