Corosex – for pH correction

Description

Corosex is a reactive magnesium oxide media used to correct low pH water and neutralize acidity. It is well suited for applications requiring substantial pH correction or higher flow conditions, and it can help reduce corrosive water conditions by neutralizing free carbon dioxide.

This 13 lb sleeve can be used alone or combined with Calcite to balance correction performance. Mixing with at least 50% Calcite is recommended to help reduce the risk of overcorrection and cementing, especially under lower flow conditions. Because Corosex is soluble to acidity, the media will require periodic replenishment.

For operation, upflow service is generally recommended when water hardness exceeds 5 grains per gallon, while downflow service is satisfactory on waters below 5 grains per gallon or when combined 50/50 with Calcite. Frequent backwashing is recommended to help prevent cementing.
