The water in my pool is extremely hard, and according to Pool School, short of draining and refilling, there aren't any other solutions out there.
I just happened to see this product, currently on sale at Sears for $3! Just to take a wild stab in the dark, is this useful at all for use in a pool (and my pool does have a SWG) as a softener?

Happy 4th everybody!
