IRON & HARDNESS	ADD IRON FILTER	ADD IRON FILTER	ADD IRON FILTER

If your water hardness is in mgl or ppm you can convert that into gpg by dividing the hardness in ppm or mgl by 17.1.

Example: 170ppm of hardness equals 9.9gpg of hardness.

Also, 1ppm of iron is equal to 5gpg of hardness when sizing a water softener.

Example: if you have 17gpg of hardness and 3ppm of iron. You should size the softener for 32gpg. 3ppm of iron times 5=15gpg of hardness. Add the original 17gpg of hardness to the 15gpg of hardness giving you 32gpg of hardness.
