What it does for your water
The PRO+AQUA MED-IONX-16 1/2 cu ft Softener Resin is replacement cation resin in a 1/2 cu ft quantity.
A cubic foot of standard softener resin is rated about 32,000 grains at full salt and about 24,000 at an efficient setting, so 1/2 cu ft is about 16,000 grains at full salt, or 12,000 at an efficient setting.
Standard 8% crosslink resin is what most residential softeners ship with.
Replace the same volume your tank holds and leave the free space above the bed the maker calls for; an overfilled tank can't backwash.
From the listing: model MED-IONX-16; resin 1/2 cu ft.
The listing gives dimensions of 15 x 13.75 x 6 inches; 27 pounds and 16,000 grains in the box.
