What is the recommended alkalinity level in a swimming pool?

The recommended alkalinity level in a swimming pool is typically between 80 and 120 parts per million (ppm). This range is crucial because total alkalinity serves as a buffer for pH levels in the water, helping to stabilize them and prevent fluctuations that could negatively impact both the pool environment and the comfort of swimmers. When alkalinity is maintained within this range, it helps to prevent corrosion of pool equipment, reduces the likelihood of skin and eye irritation for swimmers, and makes it easier to manage the overall water chemistry. It is essential to routinely test alkalinity levels to ensure they remain within this optimal range for safe and effective pool operation.
