A8011 Clack Corp Corosex, 0.66 Cu Ft Bag (50lbs)

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 five times more acidity than can calcium carbonate. This results in greatly reduced chemical usage for the same pH correction. *Please note; under certain low flow conditions, Corosex may overcorrect and create a highly basic (high pH) condition.

CONDITIONS FOR OPERATION
• Downflow service is generally satisfactory on waters with a hardness of less than five grains/gal or where it’s combined with Calcite at least 50-50. Upflow service is generally recommended with hardness exceeding five grains/gal. to prevent cementing of the Corosex bed
• A gravel support bed is recommended
• Use distributors designed for Upflow applications
• Water pH range: 4.5-6.0
• Bed depth: 24-30 in.
• Freeboard: 50% of bed depth (min.)
• Backwash frequently to prevent possible cementing
• Backwash rate: 10-12 gpm/sq. ft.
• Service flow rate: 5-6 gpm/sq. ft. but may be modified to adapt to local conditions
• Max usage 100 mg/
