Alkalinity Increaser, also known as “Alkalinity Plus” or “Alk+”, is a pool chemical used to raise the total alkalinity (TA) of swimming pool water. This product is typically made of sodium bicarbonate, which is essentially baking soda.
The primary function of alkalinity is to act as a buffer for the pool’s pH level. A proper total alkalinity level (usually between 80 and 120 ppm) prevents the pH from fluctuating wildly due to factors like rain, swimmers, or the addition of chemicals.
If your pool’s total alkalinity is too low, the pH will be unstable, which can lead to several problems:
pH Bounce: The pH will swing up and down erratically, making it difficult to maintain proper water balance.
Corrosion: Low alkalinity and pH can cause acidic water that corrodes pool equipment, such as heaters, pumps, and ladders.
Staining: It can also cause staining on pool surfaces.
Chlorine Inefficiency: An unstable pH can make chlorine less effective at sanitizing the water.
By adding Alk+, you stabilize the pH, protect your pool equipment, and ensure your other chemicals work as they should. It’s a fundamental part of maintaining proper water balance.
