3Start-UpBefore starting up a new Nature 2® Spa, clean debris andalgae out of the spa and spa equipment.Important: Do not install the new Nature2 Spa until the __spa water is clean and chemically balanced.___________Balance spa water before installing Nature 2 Spa.• pH 7.2-7.6• Calcium Hardness 200-400 ppm• Total Alkalinity 80-120 ppm• Total Dissolved Solids (TDS) 300-2000 ppmConsult your Nature 2 dealer for specific water balanceinstructions.Balance the WaterTo 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 forwater balance.Element: pH Range: 7.2-7.6If 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 watercan become cloudy. Equipment can be damaged.How to fix: Add pH decreaser.Element: Calcium Hardness Range: 200-400 ppmIf too high: Rough, discolored deposits (“scale”) will form on thespa surface and inside spa equipment.How to fix: Drain or dilute the spa water. Consult your dealer.Element: Total Alkalinity Range: 80-120 ppmIf too low: It provides no buffer so that you constantly getfluctuating pH readings, which can damageequipment 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.
