Clack (A8011) Corosex Aggressive pH Correction Media for Acidic Water 0.66 CF Bag
Corosex Aggressive pH Neutralizer 0.66 CF
Neutralization Process
Magnesium Oxide Reaction
Acidic water flows through the Corosex bed where magnesium oxide rapidly neutralizes free carbon dioxide and raises pH. The high reactivity allows for effective correction even at high flow rates of 5–6 gpm per square foot.
Media Consumption
Corosex is soluble to acidity and will slowly dissolve as it neutralizes the water. The rate of dissolution depends on incoming pH, flow rate, and water chemistry. Periodic replenishment is required based on usage and monitoring.
Mineral Addition
As magnesium oxide neutralizes acidic water, it increases hardness levels. A water softener may be necessary downstream of the neutralizing filter depending on incoming hardness and desired finished water quality.
Physical Properties
| Model Number | A8011 Corosex |
| Volume | 0.66 cubic feet per bag |
| Mesh Size | 6×16 |
| Bulk Density | 75 lbs/cu. ft. |
| Composition | Magnesium oxide (MgO) 97% minimum |
| Color | Brownish white |
| Effective Size | 1.4 mm |
| Specific Gravity | 3.6 gm/cc |
| Uniformity Coefficient | 1.7 |
Installation Requirements
| Water pH Range | 4.5–6.0 (aggressive correction from 4.0) |
| Service Flow Rate | 5–6 gpm/sq. ft. (may be modified for local conditions) |
| Backwash Rate | 10–12 gpm/sq. ft. |
| Bed Depth | 24–30 inches recommended |
| Freeboard | 50% of bed depth minimum |
| Maximum Usage | 100 mg/L acidity |
| Gravel Support | Recommended for proper distribution |
System Configuration Notes
Downflow service is generally satisfactory on waters with hardness less than 5 grains per gallon or where Corosex is combined with Calcite media in at least a 50/50 blend. Upflow service is recommended with hardness exceeding 5 gpg to prevent cementing of the media bed. Always use upflow distributors and an inline sediment filter ahead of upflow systems to prevent plugging of the lower distribution screen. Under low flow conditions, Corosex may overcorrect and create high pH; blending with Clack Calcite combines the high-flow neutralization of Corosex with the slower-reacting properties of Calcite to reduce overcorrection. Backwash frequently to prevent possible cementing, especially in hard water applications. Under certain hardness conditions, pH correction can cause hardness minerals to precipitate and solidify the mineral bed.
