Water hardness test strips

[MikeDee]

Can anyone recommend some water hardness test strips in the proper range? The ones that came with my machine from Chris' Coffee are too hard to read (colors are too close to one another for me to distinguish). Amazon carries a number of them.

I don't like any of the paper test strips for just that reason. Instead, I bought one of those "liquid" hardness test kits that are actually intended for use with aquariums. This is the one I use: https://smile.amazon.com/gp/product/B00 ... UTF8&psc=1

It's a lot more pricey than the paper strips but it's lasted me 5 years so far with no end in sight.

I have also used these strips which are about 1/2 the cost, but they are still not as good as the liquid kit.
