How To Regulate the PH of a Pool

The pH level of the water is a very important value for safe swimming and enjoying clean, crystal clear water.

Knowing how to adjust the pH levels of a pool is very important for the safety of swimmers. Along with chlorine, pH is a fundamental element for the water to be clean and clear.

But, in addition, keeping the pH at the appropriate level prevents the formation of microorganisms such as bacteria and fungi.

The pH is an index that indicates the acidity or alkalinity of the water. Normal values ​​should be between 7.2 and 7.6. This index must be measured together with that of chlorine since both the pH and chlorine are responsible for making the pool water suitable for swimming. Most experts agree that the ideal value for chlorine is 1 ppm (that is, parts per million) and the recommended alkalinity level is 125-150ppm.


If the chlorine content is high you do not smell anything or see anything suspicious in the water that alerts a person to it, because the chlorine does not smell. What smells is the reaction of the chlorine to sweat or urine, which causes the appearance of chloramine, which is highly toxic and dangerous to a person’s health.

Therefore, if the pH level is not adequate and the chlorine is high, the damage to a person’s health is serious.

For its part, alkalinity plays a very important role in controlling the pH, because if it is not correct, you will not enjoy swimming because the water will not be clean and clear.

Therefore, whether the pH is above ​​or below the normal values, the problems it causes both in the water and in our body’s is serious. Hence, it is necessary to check its levels frequently with various pool treatments.

What will happen if the pH level is below the recommended value?


If the pH value is below 7.2, the water will be acidic. The symptoms of a swimmer are itching and stinging of the eyes and nose, dryness, irritation of the throat, stinging and itching of the skin, irritation, and dryness, appearance of eczema, or redness of the skin can appear.

But not only does your body suffer. The pool equipment can corrode by the acidity of the water, especially those metal parts and those made of cement. It is also normal for the mosaic tiles to detach themselves from the walls and bottom of the pool. They could end up floating or be found at the bottom of the pool. This is not safe for a swimmer who could cut themselves while swimming.

What will happen if the pH level is above the recommended value?


If the pH value of our pool is above 7.6, the water will be alkaline. The symptoms of a swimmer are dry and irritated skin. But the biggest problem is the water, which will become cloudy, even greenish, as the algae start to appear. Even if you try to raise the chlorine levels to eliminate them, it will be impossible if you do not regulate the pH level first.

As if that were not enough, the high pH will promote the formation of lime deposits in the pool water. These lime deposits will be embedded in the pipes and other installations, affecting their functionality. The lime will also stick to walls and floors, affecting the appearance, and cleanliness of the pool.

Therefore, to know if the pH level is high we will have to measure it with a test kit that measures both the pH and the chlorine in your pool.

How to raise the pH level of a pool


If the pH level is low, you will have to use ph UP that you can buy in any pool store. There are solids, liquids, and granules and their function is to reduce the acidity of the water.

How to lower the pH level of a pool


If the pH level is high, you will have to make use of a pH DOWN, which comes in the form of both granules and liquids. With the use of the pH DOWN the alkalinity falls and the pH increases in value.

How to make your pool water crystal clear


To ensure that the water in your pool is clean and clear, it is important that the pH level of the pool water is correct, but also that of chlorine. How do you achieve that? By checking the levels regularly. It is important to know that there are aspects such as the effects of the sun, the number of people who are swimming at a certain time, and the remains of sunscreen in the water that destabilize these values. Therefore, it is essential to frequently measure the pH and chlorine levels in the pool.
