Corosex – A8011 – Clack
What is Corosex – A8011 – Clack?
Corose-x, 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.
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, Corose-x may overcorrect and create a highly basic (high pH) condition.
Under certain hardness conditions, pH correction can cause hardness minerals to precipitate out of solution, resulting in cementing or solidification of the Corose-x mineral bed. Upflow service is generally recommended with hardness exceeding five grains per gallon.
As Corose-x’s magnesium oxide neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter.
Corose-x can be effectively combined with Clack 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 overcorrection.
Physical properties

Features of Corosex:
- High degree of activity and speed of correction allowing high flow
- High capacity…less chemical usage
Operating conditions
- 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
- Use distributors designed for upflow applications
- A gravel support bed is recommended
- 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/L
