pH Minus is used to lower the pH level in your hot tub and create a stable and safe water balance. The right pH level is crucial for the disinfection to work effectively and to protect both bathers and the hot tub’s components. Always dissolve the chemicals before adding them to the water.
In a premium tub from Elsy Spa, made of stainless acid-resistant steel (4404), proper water balance is especially important to preserve the material’s finish and long-term durability.
Why is the right pH level so important in stainless steel hot tubs?
A too-high pH level can:
Reduce the disinfecting effect of chlorine
Cause cloudiness and deposits
Create an environment for bacteria growth
A too-low pH level can:
Cause corrosion on metal parts
Irritate skin and eyes
Damage rubber seals
Recommended water values for stainless steel hot tubs
For optimal water quality in your Elsy Spa, we recommend:
pH value: 7.2–7.6
Chlorine value: 1–3 mg/l (ppm)
