Where is the best place to get my water hardness tested? I've got some few-year old tests from when my well was tested, one at 180 mg/L, the other at 242 mg/L. I'm looking for a quick-and-dirty test; didn't want to have the battery of tests done on the well.

I've used the larger number to size and program my softener but would like a more current data point.

Thanks!
