POOL & SPA TIPS
Disinfecting your spa water means killing the harmful bacteria and
keeping the water clean. Superior offers two types of disinfectant
systems to choose from; chlorine or bromine based. Both have their
There are different types of chlorine treatments available to the
spa owner. We believe stabilized chlorine in tablet or granular
form is best suited for outdoor spa use. Spa Tabs are 90% available
chlorine and offer a continual slow release of disinfectant. Tabs
require a feeder or skimmer basket to dissolve. CHLOR-AID granular
chlorine dissolves completely and immediately for instant disinfection
and does not alter the pH.
There are two common types of bromine systems available. These include
organic bromine tablets and the two part liquid bromine program.
Bromine tablets are convenient and require a skimmer basket or feeder
to dispense the disinfectant. The two part bromine systems can be
added directly and immediately to the spa. Make sure the bromine
level is 3-5 p.p.m.
After using your spa, body oils, perspiration, hair and dirt accumulate
which can turn your spa cloudy. Periodic shock treatments with SPA
SHOCK will oxidize these organic contaminants. SPA SHOCK is compatible
with both Chlorine and Bromine disinfectant systems.
Water balance is important to he overall performance of your spa.
No spa's water conditions are exactly alike. The water source, location
of the spa and frequency of use all affect the water balance. Unbalanced
water can damage the equipment, make the water uncomfortable for
the user, and decrease the effectiveness of the disinfectant. Total
alkalinity, pH, and calcium hardness must be within the correct
range to balance the water.
pH is a scale indicating whether spa water is basic, neutral or
acidic. Spa water should be slightly basic 7.2-7.6.
A low pH below 7.2 leads to corrosion of spa equipment and will
irritate the skin of the bathers. The sanitizer will dissipate more
rapidly. A low pH can be corrected by adding pH BOOSTER.
A high pH above 7.6 promotes scaling on heat exchange tubes, creates
cloudy water, calcium deposits and reduces the effectiveness of
disinfecting agents. A high pH can be corrected by adding pH REDUCER.
alkalinity is a measure of the alkalines in the water. They act
as a pH buffer or a pH stabilizer preventing large changes in the
pH. The total alkalinity should be between 80 -150 p.p.m.; ideally
120 p.p.m. Tablet chlorines and bromine tend to gradually lower
the alkalinity level.
A low total alkalinity causes:
total alkalinity causes:
pH to wander
to be ineffective To raise the total
alkalinity add ALKA RISE.
the total alkalinity add pH REDUCER.
hardness is the hardness present due to dissolved calcium. The desired
range is 150-280 p.p.m.
A low calcium hardness causes: - corrosive water - staining of surfaces
To raise calcium hardness add CAL-RISE.
A high calcium hardness causes:

Spa Water Problems - Cause & Remedy
A) Organic contaminants build up.
B) Suspended particles.
C) pH high.
D) Total alkalinity too high.
E) Hardness too high.
F) Poor filtration.
G) High dissolved solids.
A) Shock treatment and SPA SHOCK. Add deskummer
B) Add SPA CLEAR. Use SPA-BALL.
C) Add pH REDUCER until pH level reads 7.2 - 7.6
D) Add pH REDUCER, adjust total alkalinity to 80 - 150 p.p.m.
E) Add PREVENT II, circulate through a water softener until
hardness is 150-280 p.p.m.
F) Dirty filter, clean with CARTRIDGE CLEANER.
G) Empty spa and refill.
A) Dissolved copper, iron and other metals from source water
A) Use PREVENT II. Have Superior check water balance.
B) Add non-foaming AGAECIDE.
C) Stop the use of fragrance.
A) High concentration of oils and organic contaminants being
agitated by jets B) Soft Water
A) Squirt DEFOAMER on foam. Use SPA-BALL or add Descummer.
B) Add CAL RISE until hardness is 150-280 p.p.m.
High calcium level, high pH, high alkalinity
Drain partially, add PREVENT II, correct pH level to 7.2-7.6
and alkalinity to 80-150 p.p.m.
High level of organic contaminants, combined chlorine.
A) pH too low
B) combined chlorine due to high concentration or organic
Shock with SPA SHOCK, add Descummer.
A) Add pH BOOSTER until level is 7.2-7.6
B) Shock with SPA SHOCK, add CHLOR-AID, SPA-TABS or LITHIUM
Chlorine / Bromine Reading
A) High concentration of organic contaminants using up sanitizers
B) Test reagents may be ineffective
A) Add sanitizers until levels are up to recommended range.
B) Replace at least once a year, keep cool and out of sunlight.
