What is the maximum recommended pH level for reducing carbonate deposits effectively?

The maximum recommended pH level for effectively reducing carbonate deposits is 7. At this neutral pH level, the conditions are optimal for preventing the precipitation of calcium carbonate and similar minerals that can lead to scale build-up. Maintaining a pH around 7 helps ensure that the water remains non-corrosive while also minimizing the potential for scaling. In contrast, higher pH levels can lead to increased carbonate stability and precipitation, which exacerbates scale formation rather than reducing it. Therefore, a pH of 7 is considered ideal in this context, as it strikes a balance between preventing corrosion and minimizing deposit formation.
