Soft is a granular product that contains a blend of finely ground Boric Acid. It is very soluble in water, and carries our pleasant green apple scent. Being virtually pH neutral at 7.0, Soft enhances water quality and comfort. It produces pleasant, smooth feeling, silky water. Soft has the ability to stabilize, or ‘buffer’ changes in pH; it is very effective after the hot tub water has been initially properly balanced. It changes the makeup of the water to stabilize, or ‘lock in’ the pH for a period of time. Soft also has corrosion, scale and staining preventing properties by keeping water in a balanced state, which protects the hot tub equipment and fixtures.
