The total alkalinity of a swimming pool should be kept sufficiently high to stabilize pH, optimize sanitizer efficiency, and help prevent corrosion, but low enough to avoid scaling and clouding of hard water. The recommendations of alkalinity in pool water fall within the range of 80-150 ppm (parts per million) of alkalinity. The higher ranges are recommended when the pool water pH will tend to drift down, as in rainy seasons.

Research studies have shown that there is clearly a relationship between pool pH and total alkalinity present in water. In general, when alkalinity increases, the pH of the pool tends to be higher. More specifically, when alkalinity is adjusted to the range of 80 to 150 ppm, it maximizes the likelihood that the pool pH will hold in the range of 7.2 to 7.8.  Which is where you want it to be.

In basic terms TA acts like a buffer for your pH level. You want your pH to be in a balanced state or ‘neutral’ optimally.

When alkalinity creeps up it makes your water alkaline which can then create a scale.  When it is low, it will make your water acidic.  When your water is acidic it is an acid.  Acid is corrosive and will eat any metals that it can find.  Yes, that means your equipment.

Keeping your pH and alkalinity balanced is essential to how your water feels, how long your equipment will last and what your water looks like.

Don’t fool yourself by thinking all you need to do is sanitize your water and shock it once a week.  Pool water balancing is also very necessary
