Clear, hygienic pool water starts with the right pH level. Only when it is within the optimal range can disinfectants such as chlorine work properly – and the water remains pleasant for skin, eyes and equipment.
In this article, you will learn why the pH level is so important, how to measure it and adjust it specifically – with the highly effective pH regulators from PROFI-Clean.
1. Why the pH level in the pool is so important
The pH level indicates how acidic or alkaline the water in your pool is. The ideal range is between 7.0 and 7.4 – so slightly neutral to slightly alkaline. Within this range, swimmers feel comfortable, chlorine works effectively, and the equipment is protected.
If the pH level is too high (above 7.6), the water can become cloudy, the chlorine effect decreases, limescale deposits, and it can cause skin and eye irritation. If it is too low (below 6.8), the water becomes aggressive, which not only attacks materials but also strains the skin.
A correctly set pH level is the foundation for all further pool maintenance – whether chlorine, algaecide or flocculant.
2. Lowering the pH level with PROFI-Clean pH-Minus Liquid
If your pool water has a pH level that is too high, you need a reliable product to lower it quickly and safely. With the PROFI-Clean pH-Minus Liquid, you can do this very easily. The product is based on an effective acid combination (including sulfuric acid) and is suitable for regular use as well as for occasional corrections.
Thanks to the liquid form, you can dose it precisely – without the hassle of dissolving like powder. Whether manually or via a dosing system: pH-Minus Liquid quickly ensures that your water is back in the optimal range – for maximum chlorine effect, clear water and a pleasant swimming experience.

3. PROFI-Clean pH-Minus Granules – the flexible solution for pools and other bodies of water
In addition to the liquid variant, PROFI-Clean also offers the proven pH-Minus Granules for effectively lowering the pH level – ideal for pools, swimming ponds, fountains and other bodies of water. The granules can be easily dosed, dissolve quickly in water and are therefore particularly user-friendly, even without a dosing system.
Whether in a private pool or in commercially used facilities: With the PROFI-Clean pH-Minus Granules, you quickly bring the water back into balance – without elaborate technology. Through targeted application, you not only protect your swimmers, but also pool walls, pipes and filter systems from limescale deposits and corrosion. A reliable alternative for everyone who values flexibility and easy handling.
4. When the pH level is too low
Not only can a pH level that is too high cause problems – a pH level that is too low also damages the water quality. The result: corrosion on metal parts, irritated eyes and chlorine that works less effectively. A value that is too low occurs less often, for example after heavy rain or after too high a dose of pH reducer.
Then a pH increaser (pH-Plus) helps. Dose it in small steps according to the manufacturer's instructions, let the filter system run and measure again after a few hours. Important: Never add pH reducers and pH increasers at the same time.
5. Measuring the pH level correctly: How to do it
Before you regulate the pH level, you naturally have to measure it. This is best done with test strips, digital measuring devices or pool test kits. The measurement should be carried out regularly – preferably 2–3 times a week, especially at high temperatures or heavy use of the pool.
Tip: Always measure at the same time of day and in deeper water (not directly on the surface) to obtain the most accurate results. Note down the values so that you can recognize changes early and take corrective action.
6. Liquid vs. Granules: Which is better?
PROFI-Clean offers you both liquid as well as solid pH regulators in granule form. But which variant is best suited for you?
-
Liquid pH regulators such as pH-Minus Liquid can be dosed particularly precisely and are ideal for automatic dosing systems or larger pools. They work very quickly and leave no residue.
-
Granules such as pH-Plus are practical for smaller pools and manual application. They are easy to store, economical in consumption and easy to portion.
Which form you decide on therefore depends on the size of your pool, your equipment and your personal preferences.
