•
pH
7.2-7.6
• Calcium Hardness
200-400 ppm
• Total Alkalinity
80-120 ppm
• Total Dissolved Solids (TDS) 300-2000 ppm
Consult your Nature

dealer for specific water balance
instructions.
Balance the Water
To find out if your spa water is balanced:
• take a water sample to your dealer to be tested regularly,
or
• ask your dealer to recommend a spa test kit for
water balance.
Element: pH
Range: 7.2-7.6
If too low: The surface of your spa can become etched.
Metal parts in the pump and plumbing will corrode.
How to fix: Add pH increaser.
If too high: “Scale” forms on the surface of your spa. The water
can become cloudy. Equipment can be damaged.
How to fix: Add pH decreaser.
Element: Calcium Hardness
Range: 200-400 ppm
If too high: Rough, discolored deposits (“scale”) will form on the
spa surface and inside spa equipment.
How to fix: Drain or dilute the spa water. Consult your dealer.
Element: Total Alkalinity
Range: 80-120 ppm
If too low: It provides no buffer so that you constantly get
fluctuating pH readings, which can damage
equipment and spa surfaces.
How to fix: Use an alkalinity increaser.
If too high: The water becomes cloudy or milky white.
How to fix: Add acid to bring alkalinity down.
