Re: Water Hardness

OK one more thing, This test has to be wrong!  I have always been told that
we have hard water around here. We all get our water from the Columbia river
yet the test I am using says that my GH is 3 dh and my KH 3 dh.  According
to the chart at Tropica this is very soft.  That just can't be, can it?  I
am using the test by Aquarium pharmaceuticals, have any of you used this
test and did you get accurate results?
