of 0-14, pH is the measure of acidity and basicity in
the water. pH levels under 7.0 are acidic while pH
levels over 7.0 are basic. The proper pH range for a
spa is 7.4 to 7.6.
High pH levels (over 7.6) can cause the following:
Scale build-up on the spa and its equipment, cloudy
water, a prematurely dirty filter, and less effective
chlorine sanitation. To correct high pH levels, add a
pH DECREASER.
Low pH levels (under 7.4) can cause the following:
Discomfort to the spa user and corrosion to the spa
and its equipment. To correct low pH levels, add a pH
INCREASER.
Note: Never use muriatic or hydrochloric acid to
adjust pH as it can damage your spa shell and
surroundings.
4. Total Alkalinity (TA): Total Alkalinity (TA) is the
measure of carbonates and bicarbonates in the water.
Low TA can cause pH to be unstable, bouncing from
one level to another, 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.To correct high TA, contact
your authorized Bullfrog Portable Spa Dealer.
5. Calcium Hardness (CH): Calcium Hardness (CH) is
the measure of dissolved calcium in the water. Low CH
(soft water) can result in staining to the spa's surface
as well as 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's
surface and equipment. To correct or manage high
CH, contact your authorized Bullfrog Portable Spa
Dealer.
6. Stain & Scale Control: Stain and scale problems are
common in hot water environments. To help prevent
and control staining and scaling, add a STAIN & SCALE
INHIBITOR.
7. Foam Control: Spa water that's polluted with body
oils and lotions, combined with high water
temperatures, can cause excessive surface foaming.
To prevent and control foam on the surface of the spa
water, add a FOAM REMOVER.
8. Clearing Cloudy Water: There are two basic
reasons that spa water becomes cloudy. First, non-
filterable liquid wastes (perspiration, etc.) have
contaminated the water. To remove these waste
substances, Super-Sanitize the water (as described
above). Second, non-filterable micro-particulate
wastes (dust, etc.) have contaminated the water. To
remove these wastes substances, use a WATER
CLARIFIER.
Note: Names of spa chemicals will vary from one
manufacturer to another. Please consult your
authorized Bullfrog Portable Spa Dealer if you have
questions.
