Royal Pool & Spa pH Plus - 1,5 kg
Powder product for increasing and stabilising the pH of water in pools and hot tubs. Active ingredient: sodium bicarbonate (min. 95%). Not classified as hazardous.
Restore low pH to balance
Fast-dissolving granules for gradually raising and stabilising water pH. Helps reduce water acidity, protect pool equipment and create the right conditions for effective disinfection.
Why is low pH a problem?
Excessively low pH means acidic, aggressive water. It can irritate the skin, promote corrosion and shorten the service life of metal and equipment components.
Raises low pH
Helps return acidic water to the recommended range suitable for bathing.
Protects equipment
Reduces water aggressiveness towards pipework, jets, pumps, heating elements and heat exchangers.
Improves comfort
Balanced pH helps reduce irritation of skin, eyes and mucous membranes.
Stabilises water care
Correct pH creates suitable conditions for disinfection and other pool-care products.
Raise pH gradually
Measure water pH and alkalinity before application. Dose the product gradually and always take a control measurement between steps.
A value suitable for effective disinfection, stable water and comfortable bathing.
Do not apply the entire calculated dose at once. Allow the water to mix after each step and measure it again.
Alkalinity stabilises pH. If it is outside the recommended range, adjust it first.
Correct application step by step
Never add the granules directly to the pool or hot tub. Dissolve them in lukewarm water first.
Measure the pH
Determine the current value using test strips. The target range is 6.8–7.2.
Check the alkalinity
Before adjusting pH, stabilise water alkalinity at 80–120 ppm.
Measure the dose
Determine the required amount according to water volume, measured pH and the instructions on the label.
Dissolve the granules
Dissolve the measured amount in a plastic container of lukewarm water and mix thoroughly.
Apply with circulation running
Distribute the prepared solution evenly along the edge or pour it into the skimmer with circulation running.
Measure pH again
Run circulation for at least 15–30 minutes. Then measure pH again and repeat the process according to the result.
