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