One of the most frequent events that happen when you own any size swimming pool is when the pH of the pool water slips down and is out of range where it needs to be to keep the water properly sanitized by chlorine and snowballs out of control. This can happen fast, especially in those hot summer months. What are the signs of Low pH in a Pool?
- Cause Chlorine By-Products(Chloramine)
- Impact chlorine effectiveness
- Eye irritation
- Cause etching of plaster, grout, stone, concrete, & tiling in concrete pools
- Vinyl surfaces will also become brittle, risk of cracks & tares
- This can result in staining & cloudy pool H2O
- Cause Irritated skin
- Affect Breathing
When organic compounds are mixed with chlorine-treated water, by-products are created. These are gases called Chloramines. Chloramines lead to that unusual chlorine smell that we might think is a sign of a clean pool. This sign is of low pH and low total alkalinity in a pool and the beginning of bad things happening to your pool.
Introduction:
Maintaining the optimal pH level in pool water is crucial for ensuring a safe and enjoyable swimming experience. pH, which stands for “potential of hydrogen,” is a measure of the acidity or alkalinity of a solution, including pool water. On a scale from 0 to 14, a pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline.
In the context of pool water, maintaining the correct pH level is essential for several reasons. Firstly, it helps to maintain water balance, preventing the water from becoming too corrosive or scaling. Secondly, it ensures swimmer comfort by minimizing skin and eye irritation. Lastly, it preserves the integrity of pool equipment and surfaces, preventing corrosion and deterioration.
However, when the pH level in a pool drops below the recommended range, typically below 7.2, it can lead to a host of problems.
