PROBLEM
Green Algae
Black Algae
Unpleasant Odor,
Burning Eyes
Colored Water
Hard Water
DESCRIPTION
Green Water
Green spots on surface
Slippery surface
Black spots on spa surface
Chlorine-like odor.
Burning sensation in eyes.
Water in newly-filled spa turns
black, blue, or brown when treat-
ed with ozone
Cloudy water
Scaling
CAUSE
Low ozone, bromine, or chlorine levels
Low algaecide levels
Low oxidizer levels
Low algaecide levels.
Combined chlorine and/or pH out of
balance
Copper, iron, or manganese in water
being oxidized by chlorine or ozone
Excessive hardness of makeup water or
building up of dissolved minerals in the
water caused by continued use of spa
chemicals.
REMEDY
Superchlorinate
Brush spa; removing algae
Vacuum spa; removing algae
Increase oxidizer residual
Superchlorinate
Brush spa; removing algae
Vacuum spa; removing algae
Increase oxidizer residual
Superchlorinate.
Balance pH to 7.2-7.6
Adjust pH to 7.2-7.6
Run filter continuously
Vacuum settled material
Use sequestering agent for
prevention
Clean filter
Filter continuously
Adjust pH to 7.2-7.6
Use scale inhibitor
Dilute with makeup water
Ozone Unit
Location varies with spa model.
Refer to specifications for
location and take note during
installation positioning.
Ozone:
Your spa is equipped with ozone as the sanitizing agent. This utilizes ultraviolet light and
offers a “hands-free” routine to spa water care. The pH must be maintained and shocking
may be needed after heavy bather loads. With the use of ozone, the periodic draining may
be needed less frequently, and the bromine odor no longer an issue. It is suggested that 24-
hour circulation is required to effectively sanitize the water, and a chlorine shock used
periodically. Contact your chemical supplier for more information.
1. There is no test kit available to test ozone presence in spa water, although a 24-hour
circulation period is recommended for clean, clear water. A clean, “after rain”
smell will be present when you open your spa cover as an indicator that the ozone
is doing it’s job.
2. A proper pH must be maintained and a routine bromine or chlorine shock is suggested.
3. the ozone system with your spa has an EverLite™ indicator mounted on the corner of the
spa cabinet. This emits a blue light when the ozone unit is functioning. EverLite will only
be lit when unit is in filtration cycle. Refer to control information and icon chart for
further instructions.
