TH and pH are among the 3 factors that make up the balance of water with TAC. They allow you to keep clean and clear water all season. To enlighten you and help you to differentiate them, here are our explanations:

TH

The tH corresponds to the hardness of the water, which indicates its concentration in limestone. It is measured in French degree (° F) and is ideal between 10 and 20 ° F. Indeed, the higher the tH, the harder the water is, that is to say, it is limestone. On the other hand, the lower it is, the softer the water.

What are the consequences?

If the water is hard ( high tH ):

The limestone is deposited on the walls, it creates white/gray spots then it can scale your filtration. In addition, this gives swimmers a risk of irritation to the eyes or skin.

If the water is soft (low tH):

First of all, it’s not because they say it’s sweet, it does not do anything to your pool. Indeed, the water gnawing the metal parts of your pool (such as your ladder, lighting), it makes possible eye irritation.

Finally, it is possible that it generates corrosion of the walls in concrete pools.

How to regulate the tH of your pool?

With hard water (above 20 ° F): First, be sure to keep the temperature of your pool water that will help scale if it is high. Second, regulate the pH of your pool between 7.2 and 7.4. Finally, add if you can a sequestering product to slow down the arrival of limestone.

With freshwater (less than 10 ° F): Use a product to increase the tH to 15 ° F and then adjust the pH of your pool.

PH

The pH corresponds to the acidity of the water and is measured on a scale of 0 to 14. The pH of drinking water is usually between 6.5 and 8.5. However, for your pool water, it is ideal between 7.2 and 7.4. The pH is evaluated on 3 levels:

1. A pH below 6.5 means that your water is acidic
2. A pH of 7 means that the water is neutral
3. PH above 7.6 means your water is basic

What are the Consequences?

Low pH: your bathing water can become aggressive on the skin, eyes and various equipment of your pool.

Neutral pH: All is well.

High pH: Water can become cloudy due to limescale settling in the pond. Thus, there will be an inefficiency of the actions of the products of treatments.

How to regulate the pH of your pool?

If it is too high (8 and 14): Use a less pH product respecting the doses provided by it. After pouring it into the water, wait a few hours (minimum 6 hours) before testing the pH of your water.

If it is too low (between 0 and 6): An acidic water makes your bathing uncomfortable. Unlike the instructions above, use a pH plus product. During this operation, be sure to leave your filtration running and wait at least 6 hours before testing your water again.

To conclude, regulate your pool water regularly so you can act on time to enjoy your bathing moments.
