whats the difference between hardness and alkalinity?

 

[reefrunner69]

hardness: The peculiar quality exhibited by water which has mineral salts dissolved in it. Such water forms an insoluble compound with soap, and is hence unfit for washing purposes.

Alkalinity: Is the ability of the water to maintain it's PH.
