The water is hard, according to drip tests 19-20 degrees of general hardness (GH) and 14 degrees of carbonate (KH), on the first day when the filter was installed, the water was drained according to the instructions, I took measurements GH fell to 0-1. KH remained the same 14 as the tap. A week later, scale formed in the kettle. I took measurements, the water returned to the indicators like tap water. Another thing is scary, yes, I can measure hardness, and some other indicators, but I don’t know if I can now drink this water, what’s with other parameters, or has it become identical to tap water, or even worse!
