By neutralizing the free carbon dioxide in the water, Corosex improves acidic water, making it less corrosive.
Corosex, a highly reactive magnesium oxide, can be used effectively where pH improvement is important and high flow rates are used. pH improvement and media consumption are affected by a number of water chemical variables. Corosex, soluble in acid, will dissolve slowly and need to be replenished at regular intervals. On a weight basis, magnesium oxide can remove up to five times more acidity than calcium carbonate. This results in the use of substantially less chemicals for the same rate of pH improvement. Attention please; In certain situations where the flow rate is low, Corosex can overtreat, creating a high pH. Under certain hardness conditions, pH improvement causes the hardness mineral to be driven out of solution, resulting in concretization or solidification of the Corosex mineral bed. Upstream service is generally recommended at hardness exceeding five grains per gallon. (Always use an in-line filter to avoid clogging the lower distribution strainer in front of an upstream system.) Corosex's magnesium oxide will increase its hardness while neutralizing the water. After neutralizing the water, the water may need to be softened. To combine the high flow neutralizing properties of Corosex with the slower reacting low flow properties of Calcite, Corosex can be effectively mixed with Calcite. This reduces the potentially high base values from over-healing.
