Sanitation: Spa water sanitizers kill microorganisms and keep
spa water clean and safe. Granular chlorine (Dichlor) or granular
bromine are both eective and safe. ese are the sanitizers
recommended by Bullfrog Spas. Chlorine and bromine are the
only two spa sanitizers approved for use in spas by the EPA in the
United States.
WARNING: Trichlor chlorine tablets should never be used
in an acrylic spa. Dissolve rate, potency and the extreme low pH
of this chemical can cause severe damage to the spa surface and
components. Use of trichlor chlorine tablets will void the Swim
Series warranty.
Bromine and Dichlor tablets are also not recommended as an
acceptable sanitizer in Swim Series spas unless an appropriate
feeding or metering device is used and the water is frequently
tested and monitored.Tablets dispensed incorrectly can lead to
excessive bromine or chlorine in the spa, which 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-lterable
contaminants, such as perspiration, laundry detergents, oils, hair
products, etc., which may build up in the water. ese substances
may cloud the water, create surface lms, and can interfere with
sanitizer eectiveness. Super sanitation in order to remove such
contaminants is achieved by “shocking” the spa water with a
non-chlorine shock (Potassium Peroxymonosulfate), enhanced
shock, granular chlorine (Dichlor), or granular Bromine (Bromine
concentrate).
Super Sanitize the water once a week by adding one
of the following:
• Non-chlorine shock 5 teaspoons (25ml) per 200 gallons
(909.2l) of water
• Enhanced shock 3.6 teaspoons (18ml) per per 200 gallons
(909.2l) of water
• Granular chlorine 2 teaspoons (10ml) per 200 gallons
(909.2l) of water
• Granular bromine 4 teaspoons (20ml) per 200 gallons
(909.2l) 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
Bullfrog Spas 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 buer 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 Swim Series 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 Swim Series 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/or soap or detergent residue combined with high water
temperatures can cause excessive foaming on the water’s surface.
For a temporary x 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
(454.6 liters).
Cloudy Water Prevention and Control: ere are two
basic reasons that spa water becomes cloudy. First, non-lterable
liquid waste (e.g. perspiration) has contaminated the water. To
remove these substances, Super Sanitize the water. Second, non-
lterable micro-particulate waste (e.g. dust) has contaminated the
water. To remove these substances use a Water Clarier as per the
manufacturer’s instructions.
Water Chemistry Troubleshooting
Prior to each spa use, check the water. If the water appears cloudy,
o color, has signicant 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 skin or lung irritation.
For assistance in handling challenges with spa water chemistry,
contact your Authorized Swim Series dealer or another service
center capable of performing a computerized water analysis.
Freeze Protection
NOTE: Your spa is equipped with a freeze protection mode.
When potentially freezing outside temperatures are detected your
control system will turn on to check the water temperature. If
heating is necessary to protect from freeze conditions your spa may
turn on and heat to a safe temperature. A notication will display
on the main control screen indicating this mode is engaged.
e EOS prmium ozone system operates automatically when
installed. Spas with EOS installed may experience a reduced need
for chemical sanitizer, allowing for the maintenance of sanitizer
levels closer to the suggested minimum recommended level of 3
PPM. Always maintain an absolute minimum of 2 PPM. e
EOS system may also potentially reduce the frequency of super
sanitization or spa shock application to an every-two-weeks
basis or less depending on usage patterns.
