WATER TREATMENT TROUBLE SHOOTING
Problem
Possible Cause
Solution
Cloudy Water
a) Organic contaminants
build-up
b) Suspended particles
c) High pH
d) Total alkalinity too high
e) Hardness too high
f) Poor filtration
g) High dissolved solids
a) Shock treatment with Spa-Shock
b) Add pH reducer until pH level reads 7.2
– 7.8
c) Add pH reducer, adjust total alkalinity to 80 -
120 p.p.m
d) Dirty filter
e) Empty hot tub and refil
f) Add Ultra-Spa and circulate the water for 60
mintues.
Coloured Water
a) Dissolved copper, iron
and other metals from
source water or
equipment
b) Algae
c) Fragrance
a) Use Prevent II
b) Stop the use of fragrances
Foaming
a) High concentration of oils
and organic
contaminants being
agitated by jets
b) Soft water
a) Squirt Defoamer on foam or add Descummer.
b) Add Cal-Rise until hardness is 250
– 500 p.p.m
Scale Deposits
a) High calcium level, high
pH, high alkalinity
a) Drain partially, add Prevent II, correct pH level
to 7.2
– 7.8 and alkalinity to 80 – 120 p.p.m
Odour
a) High level of organic
contaminants causing
combined chlorine
a) Shock with Spa Shock, add Descummer
b) Add Ultra-Spa
Eye\Skin Irritation
a) Low pH
b) Combined chlorine due
to high concentration of
organic contaminants
a) Add pH Booster until level is 7.2
– 7.8
b) Shock with Spa Shock, add Chlorine or
Bromine
No Chlorine/
Bromine Reading
a) High concentration of
organic contaminants
using up sanitizers
b) Test reagents may be in
effective
c) Test strips have expired
or been exposed to
moisture.
a) Add sanitizers until levels are up to
recommended range.
b) Replace at least once a year, keep cool and
out of sunlight.
c) Replace test strips
