What do you consider soft or hard?
I have noticed a great variation in "hardness charts" in the interpretation of water hardness in dGH. Mainly in different test kit instructions and on different pages and forums on the net.
Some say 6 dGH is hard. Some say that's medium hard. Some say that's soft.
What do you think?
