TA + is used to raise the total alkalinity of your pool water. A good alkalinity level helps keep the pH level in check. It makes the pH less sensitive to sudden weather changes or the use of excessive chemicals.
If the total alkalinity (TA or TAC) of the water falls between 100 and 150 ppm, the pH will remain stable.
Never mix with other (pool) chemicals. Always add the product to the water and never the other way around. Keep closed and store in a cool, dry place.
