How the media works

At the heart of this solution is the specialized media blend: calcite combined with Corosex. Calcite is a natural mineral that gently raises water pH by neutralizing acidity, preventing the water from wearing down pipes and fixtures. Corosex complements this by adding magnesium oxide, which accelerates the pH correction process for even more aggressive water. Together, they create a buffering shield that transforms harmful, corrosive water into a gentle, pipe-friendly flow. The upflow tank design ensures water passes evenly through this media bed, maximizing contact and treatment to effectively protect your plumbing system.
