10.1 pH value
The pH value indicates whether t

basic range. The pH scale usually ranges from pH 0 to pH 14.

Potential consequences of a pH value that is too low (acidic):
• Metal corrosion
• Attack on joints
• Skin and eye irritation
• Driving out of pool flocculant
•
Expulsion of carbonate hardness (pH value fluctuations)

Reduction in disinfection effectiveness (for chlorine and bromine)
