(866)-HTH-POOLThe Problem
Corrosive water can damage metal components, cause stains or discolored water, pitting and erosion of plaster and concrete surfaces, and wrinkles in vinyl liners. Low pH is a primary factor in corrosive water, especially for metals and vinyl liners. But low TA and low CH also contribute to corrosive water, especially for plaster and concrete surfaces.
Recommended solutions
- Low pH: Increase the pH to the proper range of 7.2-7.8 with hth® pH increaser.
- Test and adjust TA and CH to their proper ranges as needed.
- Use hth® metal & stain defense to help prevent stains or scale from forming.
Preventative maintenance
- Maintain proper water balance; pH, TA and CH.
- Monitor pH daily.
