Description

Spa-Time pH-Minus effectively lowers a high pH level in your hot tub, ensuring an optimal bathing experience. 

A balanced pH level between 7.0 and 7.6 is the basis for effective water care.

Only when the pH level is correct can care products fully unfold their effect, keeping the water pleasant for skin, hair, and eyes.

Benefits
  • easy to use
  • easily soluble
  • high chemical purity
Recommended Usage
Measure the pH level at least once a week. If necessary, lower the value to 7.0–7.6. Add the required amount of pH-Minus directly into the hot tub water with the pump running.

Dosage: 10 g per m³ to lower the pH by 0.1
Content: Concentrated acid granulate (contains sodium bisulfate)
 
Tip
If the water is very hard, it is recommended to check the pH level more frequently.

To protect your health and preserve your investment, hot tub water needs proper care. SpaTime is a range of products from BAYROL that is precisely tailored to these requirements and takes into account the special conditions that prevail in your whirlpool. For example, the high water temperatures and the introduction of air for the bubbling effect pose a particular challenge to water care. In addition, the pipe system, which is difficult to access, favors the proliferation and settlement of organic substances that have no business in the hot tub.
