• Bromine 100-120 ppm
• Cal-hypo 80-100 ppm
• Dichlor 100-120 ppm
• Liquid chlorine80-100 ppm
• Trichlor100-120 ppm

Total Alkalinity is necessary to keep your pH levels balanced, and low Total Alkalinity can also cause damage to pools systems and irritation for swimmers. Leslie’s Alkalinity Up raises Total Alkalinity levels to more acceptable ranges to prevent such harm and keep the pH where it is. Just add 1-1/2lb of Alkalinity Up for every 10,000 gallons in your swimming pool to raise the alkalinity level by approximately 10 ppm.

Importance of Total Alkalinity

Total Alkalinity Up may be one out of many chemicals you keep in your shed but just like the rest it plays a crucial role in keeping your water chemistry healthy and balanced. Having the right level of Total Alkalinity is essential for having optimal sanitizer performance, protection of your pool and the equipment, and for the comfort of the swimmers. When TA levels are off, it causes the pH to become unstable and can cause metal corrosion and staining of pool surfaces. As well as the pool water itself becomes more acidic, which will cause the occupants of the pool to have eye and skin irritation.
