What is the consequence of not maintaining total alkalinity in a pool?

Maintaining proper total alkalinity in a pool is crucial for several reasons, primarily related to water chemistry and the overall health of the pool environment. Total alkalinity acts as a buffer for pH levels in the water. When total alkalinity is too low, pH levels can become unstable and fluctuate widely, leading to potential damage to pool surfaces. This can include etching or corroding surfaces such as plaster, tile, and even certain types of liners, which may bear significant repair costs.

Furthermore, low total alkalinity can lead to water that is corrosive, which not only affects the physical surfaces of the pool but can also damage equipment, such as pumps and heaters. Maintaining an appropriate level of total alkalinity is essential for protecting both the pool structure and the pool's operational equipment, ensuring longevity and safe swimming conditions.
