Aries (AF-20-3232) 20"x2.5" 50% Calcite - 50% Corosex

The Aries AF-20-3232 combines 50% calcite and 50% Corosex to aggressively neutralize acidic well water and raise pH levels in whole-house applications. This 20"x2.5" specialty filter cartridge delivers faster correction than calcite alone, making it ideal for moderate to severe low-pH conditions.

COMPATIBILITY

Where the AF-20-3232 Works Best

The Aries AF-20-3232 fits all standard 20-inch filter housings with 2.5" diameter capacity, making it compatible with most whole-house and point-of-entry systems. The 50/50 calcite-Corosex blend is formulated for well water with pH levels between 5.0 and 6.5, where faster neutralization is needed compared to calcite-only media. Best used after sediment pre-filtration to prevent premature media clogging and ensure consistent pH correction throughout the service life.

🔧 Pro Tip: Install this filter after sediment filtration but before carbon or other polishing filters. The Corosex blend reacts more aggressively than straight calcite, so monitor your pH monthly during the first few months to dial in replacement intervals and avoid over-correction.
