water is frequently tested and monitored as excessive bromine
or chlorine in the spa can cause surface damage and component
failure.
With each sanitizer test, use either granular chlorine or bromine
to maintain the following levels:
• Chlorine Level: 3.0 to 5.0 PPM (parts per million)
• Bromine Level: 3.0 to 6.0 PPM (parts per million)
Super Sanitation or Spa Shock
Normal sanitation does not eliminate non-filterable wastes, such
as perspiration, oils, hair sprays, etc., which may build up in the
water. ese substances can interfere with sanitizer effectiveness.
Super sanitation is achieved by “shocking” the spa water with a
non-chlorine shock (Potassium Peroxymonosulfate), granular
chlorine (Dichlor), or granular Bromine (Bromine concentrate).
Super Sanitize the water once a week by adding one
of the following:
• Granular chlorine 2 teaspoons (10ml) of per 200 gallons
(757 l) of water
• Granular bromine 4 teaspoons (20ml) of per 200 gallons
(757 l) of water
• Non-chlorine shock 5 teaspoons (25ml) of per 200 gallons
(757 l) of water
NOTE: Super sanitation may be required more than once
per week for heavy usage. With ozone, it may not be necessary
to shock the water on a weekly basis, contact your authorized
Villeroy & Boch dealer for more information.
Total Alkalinity (TA): Total alkalinity (TA) is the
quantitative measurement of alkaline components (carbonates
and bicarbonates) present in water to act as a buffer against rapid
pH changes. Proper total alkalinity levels are important to ensure
optimal chemical balance in spas. Low TA can cause pH to be
unstable. To correct low TA, add a Total Alkalinity Increaser.
High TA can cause the water to be scale forming, cloudy and
corrosive to the spa and its components, as well as other pH
related problems. If the spa water has high TA, contact your
authorized Villeroy & Boch dealer.
Calcium Hardness (CH): Calcium hardness (CH) is the
measure of dissolved calcium in the water. Low CH (soft water)
can stain the spa surface as well as cause corrosion to the spa
and its equipment. To correct low CH, add a calcium hardness
increaser. High CH (hard water) can cause cloudy water as well
as rough scale build-up on the spa surface and equipment. If the
spa water has high CH, contact your authorized Villeroy & Boch
dealer.
Stain and Scale Control: Stain and scale problems are
common in hot water environments. To help prevent and control
staining and scaling, use a stain and scale inhibitor per the
manufacturer’s instructions. Add stain and scale inhibitor 3-4
days after super sanitation.
Foam Control: Spa water that contains body oils, lotions and
soap residue combined with high water temperatures can cause
excessive foaming on the water’s surface. For a temporary fix add
a foam remover as per the manufacturer’s instructions. e best
way to control foam is to super chlorinate the water; this will
destroy the soap agents that normal levels of sanitizer will not.
Add 2 tablespoons (20 ml) per 100 gallons (ca. 380 liters).
Cloudy Water Prevention and Control: ere are two
basic reasons that spa water becomes cloudy. First, non-filterable
liquid waste (e.g. perspiration) has contaminated the water. To
remove these substances, Super Sanitize the water. Second, non-
filterable micro-particulate waste (e.g. dust) has contaminated the
water. To remove these substances use a water clarifier as per the
manufacturer’s instructions.
Water Chemistry Troubleshooting
Prior to each spa use, check the water. If the water appears cloudy,
off color, has significant surface foam, or smells of excessive
chlorine/bromine, the water needs to be treated or drained. Using
the spa in these conditions could result in irritations.
For assistance in handling spa water chemistry, contact your
authorized Villeroy & Boch dealer or another service center
capable of performing a computerized water analysis.
Your Villeroy & Boch spa may be equipped with an optional
WellSpring High Output ozone purification system. Contact
your authorized Villeroy & Boch dealer for information on
periodic maintenance or replacement.
Your Villeroy & Boch spa may be equipped with the EOS
enhanced ozone purification system. Long term maintenance of
this system requires the replacement of the O3 Filter Cartridge
approximately every 2 years. Contact your authorized Villeroy &
Boch dealer for replacement cartridges and more information.
