Corosex® Filter Media: The Ultimate pH Correction Solution

Corosex® and Corosex II stand as premier solutions for neutralizing acidity and elevating pH levels in water treatment systems. Specially processed into hard, bead-like magnesia, Corosex is engineered to address acidic water conditions effectively and efficiently.

pH Correction Powerhouse Designed to neutralize free carbon dioxide in water, Corosex excels in correcting acidic water conditions, rendering them less corrosive. Its highly reactive magnesium oxide composition makes it particularly effective for substantial pH correction needs or high-flow conditions.

Efficiency and Cost-effectiveness Corosex boasts a remarkable capacity for acidity neutralization, requiring less chemical usage compared to traditional methods. On a per-weight basis, magnesium oxide can neutralize five times more acidity than calcium carbonate, resulting in significant chemical savings and enhanced cost-effectiveness.

Versatile Application Ideal for a wide range of water treatment applications, Corosex finds its place in residential, commercial, and industrial settings. Whether deployed as a standalone media or combined with Clack Calcite for optimized pH correction, Corosex delivers reliable performance tailored to diverse needs.
