What it does for your water

The Resin Pro HCRSN-05 1/2 cu ft Softener Resin is replacement cation resin in a 1/2 cu ft quantity. Crosslink: 8.

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.

Match the old bed's volume and don't top the tank up to the neck; resin needs freeboard to expand during backwash.
