Please help! I am no tech genius and need to buy a shower-head. When I
went to Consumer Reports, it ranks them according to whether the water
is hard or soft. So, is Chicago water hard or soft? Thanks.

If you're willing to spend a few bucks finding out,
go to a pet store and pick up a hardness test kit.
Aquarium owners use them for tropical fish.

Or, just ask the person in the fish section of the
pet store. They're usually familiar with the local
water conditions.
