The FLOMAG Corosex Magnesium Oxide Media is a highly reactive filtration media used to raise pH and neutralize free carbon dioxide in water. It is especially effective for substantial pH correction and higher-flow applications. Corosex can be blended with Calcite to provide balanced neutralization and help reduce the risk of over-correction.

Features:

• Helps correct acidic, corrosive, and red water conditions
• Reactive magnesium oxide provides effective pH neutralization
• Suitable for higher-flow applications requiring substantial pH correction
• 6 × 16 mesh particle size
• Soluble in acidic water and requires periodic replenishment
• Can be blended with Calcite at 90/10 or 80/20 Calcite-to-Corosex ratios

Note: Corosex may over-correct pH under certain conditions and create a basic water condition. A Calcite blend can help moderate its reaction rate.
