The pH is perhaps the most crucial parameter for your swimming pool water, and it should be kept within a specific range of values. Outside of these values, the pH can affect the comfort of bathers and reduce the action of disinfectants in the water. The pH also influences the lifespan of the equipment in your pond.
What Is Ph?
PH stands for “hydrogen potential,” It measures the concentration of hydrogen ions in water, which indicates whether the water is more acidic or basic. The pH value can vary from 0 to 14:
- A pH equal to 7 corresponds to neutral water
- Below 7, the water is acidic
- Above 7, water is essential (or alkaline)
- For swimming pool water, the ideal pH is between 7.2 and 7.4.
- Acidic water (therefore, a pH that is too low) is corrosive. It causes skin and eye irritation for swimmers and damages metal objects and various parts of the pool.
- Essential water (so too high a pH) is also uncomfortable for swimmers.
In addition, it promotes the formation of scale, which makes the water cloudy and is deposited in the form of a whitish deposit on different parts of the basin. Essential water is also conducive to the development of algae.
Automatic Ph Correction
It is possible to automate the measurement and correction of the pH using a pH regulator for the hot tub accessories. This device is installed on the filtration circuit. A pH regulator does two things:
- It measures the pH using a probe.
- It corrects the pH by injecting the appropriate product
A pH regulator allows you to maintain a constant pH of the water without constantly monitoring the water in your pond. In addition, since the pH correction is carried out continuously, the quantity of correction products is reduced compared to a weekly correction.
Causes Of Ph Variation
Swimming pool owners often find that it is challenging to maintain pH stability; this is because many factors can cause the pH of the water to vary:
- Water hardness: This value determines whether your water is more or less complicated. The more calcareous the water, the higher the pH will be, and vice versa.
- Rain: Rainwater is more or less acidic and can help lower the pH, so it is advisable to measure the pH after heavy rainfall.
- The agitation of the water: The more the water is stirred, the more carbon dioxide escapes from it, which modifies the water balance and causes the pH to vary. The use of water games or swimming against the current, for example, is likely to vary the pH.
- The temperature of the water: The higher it is, the more unstable the water’s chemical balance is, and therefore the more the pH is likely to vary.
