This table shows the ideal balanced measurements that
you are looking for in your testing results. Parts per million
(ppm), is a form of measurement used in most pool and
swim spa chemical readings. This is equivalent to one
milligram of concentration per liter of water.
Total Alkalinity 80 - 150 ppm
pH 7.2 - 7.6
Chlorine 2 - 4 ppm
Bromine 3 - 5 ppm
Calcium Hardness 180 - 250 ppm
* Recommended levels stated in this manual are based on industry standards for permanently installed and portable residential swim
spas.
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 tub 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
