WATER BALANCE TROUBLESHOOTING
PROBLEM POSSIBLE CAUSES SOLUTIONS
Cloudy Water Microscopic particles too small to filter out. Test and adjust all water balance elements
and add flocculent* to cause the particles to
combine together so they can be filtered
out. Increase filter cycle time.
High Total Alkalinity
High pH levels
High Calcium Hardness
Test these water balance elements and
adjust to recommended parameters.
Scale
(White/Grayish Deposit)
High Calcium Hardness Test calcium hardness level and treat with
sequesting agent* or perform partial drain/
refill.
Skin Eye Irritation Improper pH and/or Total Alkalinity levels Test water balance and make the appropri-
ate changes.
Excessive Foam Buildup of body oils or cosmetics If no water line is present you can try using
defoamer* to break up the contaminants
and then a clarifier* to help filter them away.
If a water line is present the spa may need
to be drained and cleaned. Either way, the
filter should be thoroughly cleaned by soak-
ing over night in bleach. An oil absorbing
sponge can help in preventing this in the
future. Increase filter cycle time.
Laundry detergent residual in swimwear Prevent by running an extra rinse cycle on
washing machine or re-rinse well by hand
Excess organic contaminants Some organic matter is prone to causing
foamy water as it breaks down in the filter
(maple leaves especially). Generally using
defoamer* to break up the contaminants,
then a clarifier*
To help filter them away followed by thor-
oughly cleaning your filter will clear up the
problem. It may however be necessary to
drain and refill your spa if the foaming is
quite excessive.
Low Calcium Hardness Test calcium hardness and if necessary
increase with calcium chloride*
Corrosion/Etching Presence of metals in water (iron, copper,
etc)
Test total alkalinity levels and if necessary
increase with sodium bicarbonate*
Discoloured Water
(Clear v. turbid water)
Presence of metals in water (iron, copper,
etc)
Treat with chelating* or sequestering agent*
Unstable pH Low Total Alkalinity levels Test total alkalinity levels and if necessary
increase with sodium bicarbonate*
pH resistant to changing High Total Alkalinity levels Test total alkalinity levels and if necessary
decrease with sodium bisulfate* or muriatic
acid*
