Dirty Filter/s
Excess oils / organic
matter
Improper sanitization
Suspended particles /
organic matter
Overused or old water
Clean filter or replace.
Shock spa with sanitizer.
Add sanitizer.
Adjust pH and/or alkalinity.
Run jet pump(s) and clean
filter.
Drain and refill spa.
Water Odor
Excessive organics in
water
Improper sanitization
Low pH
Shock spa with sanitizer.
Add sanitizer.
Adjust pH to recommended
range.
Chlorine Odor
Chloramine level too
high
Low pH
Shock spa with sanitizer
Adjust pH to recommended
range.
Musty Odor
Bacteria or algae
growth
Shock spa with sanitizer - if
problem is visible or
persistent, drain, clean and
refill spa.
Organic buildup /
scum ring around spa Build-up of oils and dirt
Wipe off scum with clean
rag - if severe, drain the
spa, use a spa surface and
tile cleaner to remove the
scum, and refill spa.
Algae Growth
High pH
Low sanitizer level
Adjust pH.
Shock spa with sanitizer
and maintain sanitizer
level.
Eye Irritation
High pH
Low sanitizer level
Adjust pH.
Shock spa with sanitizer
and maintain sanitizer
level.
Skin Irritation / Rash
Unsanitary water
Free chlorine level
above 5 ppm
Shock spa with sanitizer
and maintain sanitizer
level.
Allow free chlorine level to
drop below 5ppm.
Stains
Total alkalinity and/or
pH too low
High iron or copper in
source water
Adjust total alkalinity
and/or pH.
Use a metal deposit
inhibitor.
Scale
High calcium content in
water – total alkalinity
and pH too high.
Adjust total alkalinity and
pH – If scale requires
removal, drain the spa,
scrub off the scale, refill
the spa and balance the
water.
WATER QUALITY AND MAINTENANCE
Reagent: A chemical material in liquid, powder, or tablet form for use in chemical testing.
Sanitizer: Sanitizers are added and maintained at recommended residuals to protect bathers against pathogenic organisms
which can cause disease and infection in spa water.
Scale: Rough calcium-bearing deposits that can coat spa surfaces, heaters, plumbing lines and clog filters. Generally,
scaling is caused by mineral content combined with high pH. Additionally, scale forms more readily at higher water
temperatures.
