FUNDAMENTALS OF WATER
MAINTENANCE
(Non- FROG System)
• Testing: Test the water weekly or each time the spa is used with
convenient FRESHWATER 5-way test strips or more accurate liquid/
tablet reagent test kit per instructions. Critical parameters: sanitizer
level, pH, Calcium Hardness (CH), and Total Alkalinity (TA). Store test
equipment in a dark, cool, dry place to maintain potency.
• Water Filtration: The filtration used in HOT SPRING spas helps keep
water clean by circulating sanitizer and removing waste from the spa.
Regularly inspect and clean filters for peak performance.
• Chemical Balance/pH Control: It is important to adjust the primary
water parameters (Total Alkalinity, Calcium hardness, pH) into the
recommended ranges so that they are stabilized or balanced. Balance
the water chemistry every time you fill the spa with new water and then
during the life of that body of
water. Keeping the water in
balance prevents damage by
holding the pH in a safe range
and preventing calcium scale
formation on spa equipment.
A low pH can damage metal
components whereas a high
pH can cause high levels
of calcium to form scale.
Your dealer should provide
a detailed water chemistry
orientation soon after your
new spa is filled for the very
first time.
• The following three water components must be kept in balance to avoid
damage to the spa. Do balance these components in the order they
are listed here as each will help you balance the next using a minimum
amount of chemicals.
1. Calcium Hardness (CH) – CH is the measure of the amount
of dissolved calcium in the water. Low levels can make the
water corrosive and high levels cause scale formation of spa
components. The recommended CH reading is between
50 - 150 ppm . If the CH level is too high, lower it with the
VANISHING ACT
calcium remover per instructions. Once in
balance, the CH reading normally remains stable until new water is
added. Great care must be taken when filling the spa from a water
softener to ensure that the calcium remains in balance and avoid
damage to the spa.
2. Total Alkalinity (TA) - TA is a measure of the water’s ability to
resist changes of pH or buffer capacity. A low TA allows the pH
to fluctuate easily. The recommended TA reading is between
40 - 120 ppm . To raise the TA, use FRESHWATER pH/
Alkalinity Up (sodium hydrogen carbonate). To lower the TA, use
FRESHWATER pH/Alkalinity Down (sodium bisulfate). Once the
TA is balanced, it normally remains stable until the next drain/
refill. We recommend you check the TA reading once per month.
Raising/lowering the TA may cause the pH readings to fluctuate
widely. Ignore the pH readings on the test strip while you are
balancing the TA.
3. pH - The pH is the measure of the acidity and alkalinity.
Maintaining the proper pH level will optimize the effectiveness of
the sanitizer, preventing damage to the spa and physical discomfort
for spa users. A low pH dissipates sanitizer, causes corrosion,
and irritates spa users. A high pH level will neutralize sanitizer,
promote scaling and cloud water. The recommended pH reading
is between 7.2 - 7.8 . To lower the pH level, use FRESHWATER
pH/Alkalinity Down (sodium bisulfate). To raise the pH level, use
FRESHWATER pH/Alkalinity Up (sodium carbonate).
• Water Conditioners:
Spa fill water varies from location to location and
user to user, therefore it is important to consult with your dealer for an
appropriate program.
a.
VANISHING ACT
– High levels of calcium and some minerals
can be removed from the water with the single use VANISHING
ACT
. High calcium levels can cause scale formation on the spa
equipment and shell.
b. CLEAN SCREEN pre-filter –The CLEAN SCREEN pre-flter
should be used at every fill and top-off to remove contaminants
from the fill water, especially iron, copper, and manganese.
Many water sources including well water contain high
concentrations of minerals that can cause staining of the shell
and plastics.
c. Stain and Scale control – For water high in calcium and minerals,
it may be necessary to use an anti-scalant like Stain and Scale
control. As water evaporates from your spa and new water is
added, the amount of dissolved minerals like calcium, copper,
iron, and manganese will increase. (Minimize evaporation by
keeping the cover on the spa whenever possible.) High iron or
copper content in the water may produce green or brown stains
on the spa.
d. Foam Inhibitors - Soap is introduced into the spa water from
users’ bodies and swimming apparel and can cause the spa
water to foam when the jets are used. Low levels of calcium
hardness (soft water) can increase foaming. Although ozone can
oxidize soap residual, it may become necessary to add Foam
Inhibitors to suppress the foam. Excessive soap in the water
may require a water change to resolve.
• Oxidizers:
Ozone and Monopersulfate (MPS) are oxidizers used to
prevent the buildup of contaminants, maximize sanitizer efficiency,
minimize combined chlorine, and improve water clarity. They are
to be used in conjunction with EPA registered sanitizers. The
FRESHWATER
III high output ozone system uses Corona Discharge
technology to produce a high concentration of ozone which is injected
into the spa water 24 hours per day.
FRESHWATER
Chlorine-Free
Oxidizer, Monopersulfate (MPS) is a granular oxidizing chemical.
• Sanitizers: Maintaining the recommended residual level of an EPA
registered sanitizer at all times will decrease the occurrence of unsafe
bacteria and viruses in your spa water. The recommended Free
Available Chlorine (FAC), the amount of available chlorine sanitizer,
is 3.0-5.0 ppm or 0.5-1.0 ppm with @ease SmartChlor Chlorine
System . A low FAC can allow bacteria and viruses to grow rapidly in
the warm water, and a high FAC can cause discomfort to the user’s
eyes, lungs, and skin. Each sanitizer carries its own instructions
regarding how much to use and when to add it to the spa water.
Consult your dealer for their recommendations and instructions on
proper sanitizing of the spa.
