Our city water comes from a well and is very hard, rich in sulphates, magnesium, chlorides and also quite rich in sulphates. I brew beer and profile my water to match the style of beer I'm brewing (yes, the type of water matters to the style of beer). So I tested my R/O water in a lab so I can salt it properly. For a correct profile with these filters I was impressed by the water report (see image)
