pH Correction Vessels

Restore balance to acidic or low-pH water sources with our range of pH correction vessels, designed for use in residential, commercial, and borehole water treatment systems. These vessels are filled with specialised alkaline media such as Calcite, Aquastab, or Corosex, which dissolve gradually to raise the pH and neutralise corrosive water conditions.

Ideal for treating water that is below pH 7, pH correction systems protect plumbing, geysers, fittings, and appliances from copper leaching, scale instability, and metal corrosion. Vessels are available in a range of sizes to suit varying flow rates and household or site demand.

This collection includes:
• Pre-Filled pH Correction Vessels – Ready-to-install with Calcite or blended media
• Empty FRP Vessels – 10×35 to 13×54 and larger, for custom media loading
• Manual & Automatic Valve Options – For simple or scheduled backwashing
• Calcite, Aquastab & Corosex Media – For gradual pH increase and remineralisation
• Gravel Support Beds & Fill Funnels – For correct installation and servicing
• Blended pH & Hardness Correction Systems – Combined with softening or Siliphos where needed
