No, you would not see any changes on the water test. Our units work differently compared to the traditional water softener. It changes the crystal texture of the carbonates to make them stay in the water, but not stick on the pipe surface/fixtures/shower head. It feels like the water was softener, but the water hardness test didn’t show up. Easy lather up for the soap, better physical sensation, gradually disappearing scale and unobstructed water fixture. All the benefits for a family use will let you know.
