This is all you need to know about the pH regulation

One of the most important elements in the pool is the pH level. Despite being very known measure, a lot of people don’t know how it works. And you, what do you know about the pH regulation?

What is the pH level?

PH measures the alkalinity of a solution; that is to say, its acidity. In the case of swimming pools, it measures the acidity of the water. It is measured on a 14-point scale, being 7 the known neutral pH. This means that the water is not alkaline or acidic.

How does this affect the pool water?

Swimming pools require maintenance from chemical products that keep pools in optimal conditions for bathing. These elements together with other external factors such as rain or wind can alter some parametres of the water.


To avoid these imbalances and to keep the pool always at adequate levels, it is recommended to carry out a pH measurement occasionally.


Chemical products can often be ineffective due to an unbalanced pH. If you want to know the pH level of your pool, you must first know that the level will be adjusted when it is between 7.2 – 7.6.


To know where the water is on the scale of pH, there are different products that measure it in a very simple way.

PH analysers

This analysers are the most economical method to analyse this parameter. There is a very simple way to do it, although it takes some time. There are different formats: pills, strips or drops.


You must take a sample of the pool water if you want to know your pH level. Apply it in the format you have chosen and wait for it to react. Once it has done, you will see that the water or the strip, depending on the format, will have changed the colour.


Then you can check the result of the colour and compare it with the sample that is included in the product. This sample will indicate this parameter of your pool.

Smart analysers

Besides these analysers, there are some more complete ones, smart water analysers. These will help you to know the status of your pool more quickly and without doing anything.


The Blue Connect GO is a smart water analyser that measures parameters in real time. You only need to look at the result through an app and you will know if the pH is out of adjustment at the moment. We tell you more about this product here.

Regulate the pH level of your pool

What to do if after measuring the pH, it is out of adjustment? If you have already measured it and it turns out that it does not adjust to the values, you have two possibilities. If the pH level is above 7.6 it has too much acidity and therefore you will have to use a pH reducer and stabilize it.


On the other hand, if it is below 7.2 you should use a pH increaser to increase the acidity of the water.


Regulating all parametres of the pool water is something simple that must be monitored often to keep the water healthy and crystal clear even outside the bathing season.
