Corosex, a highly reactive magnesium oxide, can be effectively used where pH recovery is important and high flow rates are used. pH recovery and media consumption are influenced by a range of water chemistry variables. Corosex, which is soluble in acid, will slowly dissolve and should be renewed at regular intervals.

If we think on a weight basis, magnesium oxide can get up to five times more acidity than calcium carbonate. This results in less use of the chemical in large quantities for the same pH correction. Attention please; In certain cases where the flux is low, Corosex can create a high pH by over-curing it.

Under certain stiffness conditions, pH healing causes the hardness mineral to be thrown out of solution, resulting in concrete or solidification of the Corosex mineral deposit. Upstream service is generally recommended with a hardness of five grains per gallon. (Always use an in-line filter to prevent clogging of the downstream filter in front of an upstream system.) Corosex's magnesium oxide will also increase water-neutral stiffness. After neutralizing the water, the water may need to be softened. With Corosex's highly aggressive neutralizing feature, Corosex can be effectively mixed with Calcite to combine the slower reacting low-flow property of Calcite. This, in turn, reduces the potentially high base values ​​that result from overcrowding.
