Maintain the levels daily at the appropriate values: pH: 7.2–7.8 and total alkalinity: 100–150 ppm.
When testing shows higher values, add 15 g per 1,000 L of spa water to lower the pH by approximately 0.5 and the alkalinity by about 6 ppm.
Before adding the product to the spa, dissolve it by mixing it with water in a clean plastic container. Pour the resulting solution into the spa water at several locations.
The spa must be running when adding the product.
Wait 15 minutes, then check the pH and alkalinity again.
Repeat the procedure until the levels reach the appropriate values.

FAQ



The pH Minus product for spas generally works quite quickly, often within 10 to 30 minutes, depending on water circulation and temperature. After adding the product with the pump running, let the water circulate, then test the pH again to see if the value has returned to the ideal range. If necessary, a small adjustment can be made, always avoiding overdosing.


The pH of a spa can rise for several reasons: the water temperature, the action of air jets, excessive alkalinity, or the use of certain treatment products. Hot, agitated water naturally releases carbon dioxide, which raises the pH over time. Regular maintenance, frequent pH testing, and a proper alkalinity balance help limit these fluctuations and keep your spa water more stable.

To lower a pH that is too high in a spa, use a "pH Minus" product (pH reducer for spas). First, measure the pH, then add the quantity indicated for the spa's volume, always with the pump and jets running to ensure the product is evenly distributed. After 15 to 30 minutes, test again to make sure the pH is back within the correct range. It's better to correct the pH in several small steps rather than lowering it too much all at once.

To raise the pH of your spa water, you need to use a "pH Plus" product specifically designed for spas. Pour in a small amount, according to the dosage recommended on the packaging and the volume of your spa, then let the jets run to thoroughly mix the product. After 15 to 30 minutes of circulation, retest the pH to check if the water is now within the ideal range. It's always best to raise the pH gradually rather than adding too much product all at once.

The pH indicates whether the water is acidic or basic on a scale of 0 to 14 (7 = neutral). In a spa, the ideal range is 7.2 to 7.8: it maximizes comfort (less eye/skin irritation), maintains good disinfectant effectiveness (chlorine or bromine), and preserves the equipment. A pH that is too low makes the water corrosive and irritating; a pH that is too high promotes scale, turbidity, and reduces the action of the disinfectant.


Low pH in a spa often makes the water feel “aggressive.” You may notice eye and skin irritation, a stronger chemical smell, and even early signs of corrosion on metal components or spa equipment.

On the other hand, high pH usually leads to cloudy water, calcium deposits on the spa surfaces and jets, and reduced effectiveness of your sanitizer (chlorine or bromine). In both cases, the water becomes less comfortable and harder to balance, which signals that it’s time to correct the pH.



The ideal pH for a spa is generally between 7.2 and 7.6. Within this range, the water is more comfortable for the skin and eyes, the sanitizer (chlorine or bromine) works effectively, and the spa equipment is better protected against corrosion and scale buildup. A well-balanced pH is the foundation of good water quality in a spa.


First, stabilize total alkalinity at 100–150 ppm. Proper alkalinity buffers pH and limits roller coasters. Then, fine-tune pH.
