Alkalinity refers to the quantity and type of compounds present in the water that shift the pH above 7.0. Water with high alkalinity tends to be more strongly buffered. Buffering will reduce the tendency of the pH to shift. Add sodium bicarbonate to increase alkalinity (buffering capacity) and calcium chloride for hardness. Testing takes 2 minutes. Range: 0 to 200 ppm.
