Master Clear Alkalinity Up – 2 lb. – Powder Alkalinity increaser

Master Clear Alkalinity Up is a powder that can be added directly to your spa’s water or can be dissolved in water, to increase the alkalinity levels in the spa.  The primary component is sodium bicarbonate (which is the best method for raising alkalinity).  The ideal Total Alkalinity range is between 80 & 100 ppm, with a tolerance range between 60 & 180 ppm.  Alkalinity is most important in buffering the pH levels in your spa’s water, & keeping the pH from “bouncing” or going out of whack.
