IF YOU ARE USING TAP WATER, YOU NEED TO TEST THE HARDNESS WITH OUR STRIPS, THE REQUIRED DOSES WILL BE LOWER.
* For accurate results we recommend to use a EC Meter
* The values shown in the water hardness table are expressed in ppm of CaCO3, which indicates the amount of calcium present in the water.
The EC / TDS expressed in ppm should not be mistaken with the water hardness, these values refer to the salt content in the water and might not be accurate information on the hardness. Information about the water hardness can be obtained by asking the local town hall or visiting its website.
