Corosex F is a filter media that is an excellent acid neutralizer of free carbon dioxide in your water. This water acid neutralizing media works great with our Acid Neutralizing Water Treatment System, and it's best used where pH water correction is substantial. Each bag is .66 cubic foot.
By neutralizing the free carbon dioxide in water, Corosex can correct acidic water conditions and render it less corrosive. It's a highly reactive magnesium oxide, 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, it will slowly dissolve and will need to be refilled.
On a per weight basis, magnesium oxide can neutralize five times more acidity than can calcium carbonate. This results in greatly reduced chemical usage for the same pH correction.
Under certain hardness conditions, pH correction can cause hardness minerals to precipitate out of solution, resulting In cementing or solidification of the Corosex mineral bed. Upflow service Is generally recommended with hardness exceeding five grains per gallon. (Always use an in-line filter ahead of an upflow system to prevent plugging of the lower distribution screen.)
As Corosex's magnesium oxide neutralizes the water, hardness can increase and a softener may become necessary after the neutralizing filter. Corosex can be effectively combined with Calcite to combine the high flow neutralization properties of Corosex, along with the slower reacting low flow properties of Calcite, reducing potentially high basic properties due to over-correction.
