How to Install Your Aries pH Neutralizer Cartridge
- Shut off water supply and relieve pressure from your Big Blue housing by opening a downstream faucet
- Remove the housing sump using a filter wrench, discard old cartridge, and rinse the sump thoroughly
- Insert the AF-20-3232-BB cartridge into the housing with either end facing up, as this is a double-open-end design
- Reinstall the sump with a new o-ring if needed, turn water supply back on slowly, and check for leaks
- Flush the system for 5 minutes to remove any fine media particles before normal use
Housing Requirements
The Aries AF-20-3232-BB fits all standard 20-inch Big Blue housings with 4.5-inch diameter capacity from brands including Pentek, Culligan, Hydronix, and GE. This cartridge is designed for whole-house pH correction applications where acidic water (pH below 7.0) is causing corrosion in copper pipes, fixtures, or appliances. The 50/50 calcite-corosex blend provides faster pH correction than calcite alone while maintaining stable long-term performance.
