I need to know a simple way to test the lime level in the tap water since I am going to install a new dishwasher to determine what amount of salt I need to use. There are settings to be done, or even no salt at all if lime level is very low.

I had a testing strip which I cannot find.

Can you help? Any clues ?
thanks

It is possible to measure the level of hard water by obtaining a free water testing kit. These are supplied by most water softening companies.
