Water balance is important as it ensures that the mineral content of the water is in an appropriate state to protect the spa surface and equipment and make spa water more comfortable to bathe in. Water balance is affected by a wide range of variables – the quality and source of the water, what chemicals are added to the water, the exposure of the spa to weather conditions and so on. Due to the small water volume, raised water temperature and rapid agitation, chemical reactions occur much more rapidly in spas than they do in a pool environment, making water balance even more critical. A proper balance of chemical factors such as total alkalinity, pH and calcium is needed for the sanitiser to work correctly, the water to be pleasant to bathe in and to prevent scaling or corrosion of the spa surface and equipment.
BioGuard SPA Shield raises calcium hardness to help prevent corrosion of equipment and etching of surfaces.
BioGuard SPA Comfort Up raises pH to help prevent equipment corrosion, surface damage, and skin and eye irritation.
BioGuard SPA Performance Up raises Total Alkalinity to help prevent equipment corrosion and surface damage and helps control the pH.
BioGuard SPA Aquality slowly lowers pH and decreases Total Alkalinity to help prevent scale build-up, cloudy water and eye irritation.
BioGuard SPA Perfect Balance is a phosphate buffer that maintains stable pH, softens water and inhibits corrosion in spas and hot tubs.
