Corosex®
By neutralizing the free carbon dioxide in water, Corosex can correct acidic water conditions and render it less corrosive.
Corosex, being a highly reactive magnesium oxide, is used most effectively where pH correction is substantial or high flow conditions are in use.
pH correction and media consumption are affected by a number of water chemical variables. Being soluble to acidity, Corosex will slowly dissolve and will need to be replenished periodically.
On a per weight basis, magnesium oxide can neutralize much more acidity than can calcium carbonate, (five times as much). This results in greatly reduced chemical usage for the same pH correction.
Please note, under certain low flowconditions, Corosex may over-correct and create a highly basic (high pH) condition. Under certain hardness conditions, pH correction can cause hardness mineralsto precipitate out of solution, resulting in cementing or solidification of the Corosex mineral bed.

If Corosex is used alone and not in a blend with Calcite, upflow service is generally recommended with hardness exceeding five grains per gallon.
(Always use an in-line filter ahead of an upflow neutralizer to prevent plugging of the lower distribution screen.)
As Corosex’s magnesium oxide neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter.
Corosex can be effectively combined with Clack Calcite to combine the high flow neutralization properties of Corosex, along with the slower reacting lowflow properties of Calcite, reducing potentially high basic properties due to overcorrection.
We recommend Corosex to be blended with Calcite at a ratio or 90% Calcite and 10% Corosex, or 80% Calcite to 20% Corosex. Corosex works better when used with a backwashing neutralizer filter. |
