FLOMAG Corosex Magnesium Oxide Media

The FLOMAG Corosex Magnesium Oxide Media can correct red water conditions and render it to a non-corrosive condition by neutralizing the free carbon dioxide in water. Corosex, being a reactive magnesium oxide, is used most effectively where pH correction is substantial or high flow conditions are in use. Corosex being soluble to acidity, will have to be replenished periodically. Please note, under certain conditions, Corosex may over correct and create a basic condition. This product is 6 x 16 mesh.
Corosex may be effectively combined with Calcite to combine a high flow neutralization properties of Corosex, along with the slowing reacting low flow properties of Calcite reducing potentially high basic properties due to over correction.

We recommend Corosex to be blended with Calcite at a ratio of 90% Calcite and 10% Corosex, or 80% Calcite to 20% Corosex.
