WATER MAINTENANCE – TROUBLE-SHOOTING GUIDE
PROBLEM
POSSIBLE CAUSES
HOW TO FIX IT
CHLORINE ODOR
Excessive chlorine
Shock water with oxidizer/non-chlorine
shock treatment
Low pH
Adjust pH if necessary
WATER ODOR
Low levels of sanitizer
Adjust sanitizer level with chlorinating
granules
pH out of range
Adjust pH if necessary
Bacteria or algae growth
If sanitizer has already been adjusted, it may
be necessary to perform a system flush
CLOUDY WATER
Dirty filters or inadequate
filtration
Clean filters with filter cleaner and adjust
filtration
Unbalanced water chemistry Test and adjust chemistry levels
Old water
Drain, clean inner shell and refill with filtered
water
CLOUDY AND
GREEN WATER
Total alkalinity levels are low Use a pH increaser
Sanitizer levels are low
Apply oxidizer/non-chlorine shock treatment
and adjust sanitizer
CLEAR GREEN
WATER
High iron or copper content
Use a sequestering agent
Sanitizer levels are low
Apply oxidizer/non-chlorine shock treatment
BROWN WATER
High iron or manganese
level
Use a sequestering agent
FOAMING
High levels of body oils,
lotions, soap, etc.
Add small amount of defoamer, an enzyme
product and check water chemistry
Low calcium hardness
Use a calcium hardness increaser
Unbalanced water chemistry Test and adjust chemistry levels
EYE OR SKIN
IRRITATION
Unsanitary water
Adjust water chemistry according to testing
results
Total chlorine level above
5 ppm
Apply oxidizer/non-chlorine shock treatment
Poor sanitizer/pH levels
Adjust pH level as necessary
SCUM DEPOSITS
AT WATERLINE
Body oils and dirt
Use multi-purpose cleaner to clean swim spa
surface and add enzyme product to swim
spa water
CHALKY, WHITE
SCALE DEPOSITS
Minerals present in
the water and lack of
sequestering agent use
When swim spa is drained, use a
multi-purpose cleaner or white vinegar
and scrub with a soft cloth
PITTING OF METAL
FIXTURES
Low pH or total alkalinity
Check water chemistry and adjust
