Pool/spa: avoid traces and limescale deposits?

Naturally present in water, limescale causes marks and stubborn deposits on the walls of swimming pools and spas. A too high concentration of limescale causes discomfort to bathers and accelerates the deterioration of equipment. In this article you will find tips on how to prevent limescale deposits.

What is limestone ?

It is the combination of too much calcium carbonate and magnesium carbonate that forms hard water. Water hardness is caused by :

• Too high a pH level
• Natural water quality
• Too high a water temperature.

• Water hardness also depends on your geographical location and the mineral content of the soil. It is important to know the water quality in your area, because it can explain the hardness or softness of your pool. This will allow you to adapt your pool and spa water treatment to the characteristics of your region. 
• A too high pH leads to the formation of scale, which is why it is important to measure the tH of your pool .

What are the consequences for my pool ?

Limescale can impair the filtration of the pool and encourage the encrustation of impurities and the growth of algae. Too much limescale can block the filtration system and cause severe damage to liners or walls.

How to prevent limescale?

Your pond should be maintained on a regular basis to avoid having to deal with this problem.

• Check the pH: It should be between 7 and 7.4 ideally
• Check the tH (water hardness): the water is perfect between 10°f and 20°f (100 to 200 mg/l or ppm)
• Perform a pool weekly maintenance
