interfere with sanitizer effectiveness. Super Sanitizing (or
“shocking” or “Super Chlorinating”) the spa water is achieved
when the sanitizer level reaches or exceeds 10.0 PPM with
granular Chlorine (Dichlor), or 22.0 PPM with granular Bromine
(Bromine concentrate). Super Sanitation can also be
achieved with a non-Chlorine shock (Potassium
Peroxymonosulfate or equivalent). Contact your authorized
Bullfrog Spa dealer for assistance.
When Super Sanitizing your spa water, and providing that you
are available to attend to the safety of any children present,
you should allow the high level of sanitizer to off-gas by
opening the spa cover at least half way for a minimum of 20
minutes. Failure to allow high concentrations of sanitizer to
off-gas with the spa cover open will cause the underneath
side of the cover to discolor and degrade. Such damage to
the spa cover is not covered under the terms of your spa’s
warranty.
WARNING: Never leave an open spa unattended,
especially if there are children present.
IMPORTANT: Always allow the chlorine level to fall below 5.0
PPM (11.0 with Bromine) before entering the spa water.
pH Control
Proper pH balance is extremely important in providing water
that is comfortable to the user, and preventing damage to
the spa and equipment. The measure of acidity and basicity
in the water is called pH. The pH scale ranges from 0-14.
Levels of pH less than 7.0 are acidic while pH levels greater
than 7.0 are basic. The proper pH range for a spa is 7.4-7.6.
High pH levels (greater than 7.6) can cause scale build-up on
the spa and its equipment, cloudy water, a prematurely dirty
lter, and less effective sanitation. To correct high pH levels,
add a pH decreaser.
Low pH levels (less than 7.4): can cause discomfort to the spa
users, rapid dissipation of sanitizer, and corrosion to the spa
equipment. To increase pH levels, add a pH increaser.
NOTE: Never use Muriatic or Hydrochloric acid to adjust pH as
it can damage the spa shell and surrounding components.
Total Alkalinity (TA)
TA is the quantitative measurement of alkaline components
(carbonates and bicarbonates) present in water, which if
properly adjusted, 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 the pH to be
unstable causing the water to be corrosive or scale forming
to the spa and its equipment. To correct low TA, add a Total
Alkalinity Increaser. High TA can cause scale build-up, cloudy
water, as well as other pH problems. If the spa water has
high TA, contact your authorized Bullfrog Spa dealer
for assistance.
Calcium Hardness (CH)
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 CH 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, it is preferable to
either dilute the water’s hardness by blending the water with
water from a water softener, or by the addition of a special
water softening chemical (contact your authorized Bullfrog
Spa dealer). IMPORTANT: Never ll the entire spa with soft
water unless an appropriate mineral supplement is
immediately added (contact your authorized Bullfrog
Spa dealer).
Stain and Scale Control
Stain and scale problems are common in hot water
environments. To help prevent and control staining and
scaling, add a Stain and Scale Inhibitor.
Foam Control
Spa water that is polluted with body oils and lotions,
combined with high water temperatures, can cause
excessive surface foaming. For a temporary x, add a Foam
Remover. The best way to control foam is to Super Sanitize the
water; this will destroy the soap agents that normal levels of
sanitizer will not.
Cloudy Water Prevention and Control
There are two basic reasons that spa water becomes
cloudy. Non-lterable liquid waste (e.g. perspiration) have
contaminated the water. To remove these substances, Super
Sanitize the water. Or, non-lterable micro-particulate waste
(e.g. dust) has contaminated the water. To remove these
substances use a Water Clarier.
Starting the Spa with New Water
IMPORTANT: Never ll the spa with soft water unless an
appropriate mineral supplement is immediately added. If
your water is extremely hard, it is preferable to either dilute
the water’s hardness by blending the water with water from a
water softener, or by the addition of a special water softening
chemical. For more information, contact your authorized
Bullfrog Spa dealer.
Step 1: Add the prescribed dose of Stain and Scale Inhibitor
while lling the spa. This will provide the initial protection
