Water Testing

Water Testing

Before testing your water always run pumps on high for at least 1-minute for better accuracy. The Natural Hot Tub Company’s ® Water Treatment and Conditioner helps stabilize the pH and alkalinity levels. When making any adjustments to your hot tubs & spas water by adding products you should only add one product at a time. When adjusting pH and alkalinity, wait 24 hours before retesting your water. See Hamilton Index for more information on proper hot tubs & spas water balance.
