Many people have water in their apartments that is far from ideal, which is why filtration systems are becoming increasingly popular.
However, sometimes doubts arise: sometimes the water seems quite normal.
What methods will help you determine the degree of hardness yourself?
A cup of tea
It is best to use the method on leaf tea. Take the tea leaves, put them directly into the cup and wait a few minutes. If a film appears on the surface of the liquid, then you definitely have water with high hardness.
Pocket mirror
This method is also one of the simplest and most accurate. You need to pour just one drop of water on the mirror and wait for about five minutes.
Then evaluate the result. The presence of a trace with a clear whitish tint indicates that the water quality is far from ideal.
Go to the pet store
Owners of home aquariums always analyze water hardness indicators, as this is necessary to create comfortable and safe conditions for pets.
That is why specialized stores sell special strips that quickly and accurately determine the hardness indicators.
