Keeping a pool in perfect condition requires paying attention to several factors, including the water alkalinity.
What is the alkalinity of a swimming pool?
A proper balance of alkalinity helps stabilize pH and keep the water crystal clear and safe for bathing. In this article, we explain what is alkalinity, its relationship with pH and how to correct it if it is outside the recommended levels.
The total alkalinity of a pool is the measure of the concentration of alkaline substances dissolved in the water, mainly carbonates, bicarbonates and hydroxyls. This parameter acts as a buffer that stabilizes the pH, avoiding sudden fluctuations that could affect the quality of the water and the effectiveness of the chemicals used in its treatment.
What is the difference between pH and alkalinity?
Alkalinity and pH are often confused, but they are different concepts:
- pH- Measures the acidity or basicity of water on a scale of 0 to 14.
- Alkalinity: indicates the ability of water to resist changes in pH.
A well-balanced alkalinity helps maintain a stable pH, preventing it from becoming too acidic or basic. To control these parameters, it is essential to carry out regular tests with testing equipment. water measurement and analysis.
What happens if the alkalinity of the pool is low?
When alkalinity is below recommended levels, the pH becomes unstable and can fluctuate easily. This can cause:
- Corrosive water that damages pool surfaces and equipment.
- Irritation to the eyes and skin of bathers.
- Less effectiveness of disinfectant products, such as chlorine.
To avoid these problems, it is important to regularly monitor alkalinity levels and make adjustments when necessary.
What happens if the alkalinity of the pool is high?
If the alkalinity is too high, problems may arise such as:
- Cloudy water due to mineral precipitation.
- Blockage in filtration systems.
- Difficulty adjusting pH, which can reduce the effectiveness of disinfectants.
In these cases, it is necessary to reduce the alkalinity using the appropriate products to balance the water levels.
What is the ideal level of alkalinity in pool water?
The recommended alkalinity level total in a swimming pool is between 80 and 120 ppm (parts per million). This range ensures that the pH remains stable and that the water retains its quality.
How do you alkalize pool water?
How to increase the alkalinity of the pool
If the alkalinity is low, you can increase it by adding baking soda in the recommended doses. This compound raises alkalinity without significantly altering the pH. Furthermore, the use of dosing systems helps manage pool chemicals in a controlled and efficient manner.
