I'm a bit confused about water softener sizing. I followed the water sizing calculation here:
http://www.qualitywatertreatment.com/water_softener_sizing.htm
2 people x 75 gals x 9 gpg + 0.0 iron = 1350 grains per day, which they recommend a 24000 grain capacity.
So I figured a unit with 0.75 cubic feet of resin would suffice. When I go Aquatell's product page for the Fleck 5600 SXT - 24000 grain, it says "a good choice for a home with hardness less than 5 grains per gallon. If your hardness is higher than this, you really need a bigger softener."
So is this true? I'm not sure what size I should be getting.
