    The total alkalinity of pool water is directly correlated to the pH level of the water, inextricably linked like peanut butter and jam. When the pH level goes down, so goes the alkalinity, tilting the water from a neutral state to an acidic one. If this is happening in your pool, it’s probably due to one of the following reasons: The first one is r...

    When a pool’s alkalinity measures below 80 ppm it can cause unwanted side effects, including: 1. Fluctuating pH levels.Wild swings in the water’s pH will occur if the alkalinity is low. This is also known as pH bounce, and is the result of the pool water not having an adequate buffer, aka the proper alkalinity level. When pH bounce occurs, you’ll s...

    Now that you know how low TA negatively affects your pool, raising it should be a top priority. There’s 2 ways you can do this, both starting with testing the waterso you know how high you’ll need to raise the alkalinity level.

    Balancing your pool can be tricky, and you may find after raising the alkalinity that the pH level is now too high. You can lower the pH by adding a measured amount of muriatic acid (hydrochloric acid) or dry acid (sodium bisulfate) to your pool water. Sulfuric acid is another option, but it significantly raises your TDS levelstoo. Muriatic acid is...

    Whether it’s through baking soda, or soda ash, raising alkalinity in a pool is easy to do. By testing and paying attention to the correct dosage amount, you can have your swimming pool water rebalanced and back to a swimmable condition within a matter of hours.
