## Calculators – correction of water parameters

Below we provide two useful tools - calculators. With their help, it is easier to correct the parameters of conductivity H and general hardness GH in the tank. It often happens that it is necessary to correct the H or GH parameters, and at the same time calculate, for example, what value of specific conductivity H will be in our water in a 55-liter tank after changing 10 liters of water with a specific conductivity of H = 240, if it had conductivity before the change specific H = 311 μS.
You need to remember that the calculations are accurate, you need to know as accurately as possible the amount of water in the tank and, of course, the value of specific conductivity H or general hardness GH.

Correction of the specific conductivity (H) of water

Correction of the specific conductivity of water

Using the calculator is simple: enter the amount of water in the tank and its current conductivity value H in μS, as well as the amount of water exchanged and its conductivity in μS. And press Calculate

Correction of general water hardness GH

Correction of total water hardness GH

Using the calculator: enter the amount of water in the tank and its current value of the general hardness GH and the amount of water to be changed and its general hardness GH. And press Calculate ...

You need to know that the measurement of the specific conductivity H will not tell us exactly about the value of the general hardness GH, and conversely the measurement of GH will not tell us exactly about the specific conductivity. This is due to the fact that each mineralizer gives a different specific conductivity H with the assumed value of the general hardness GH. Some mineralizers on our market for 1 degree GH give e.g. approx. 40 μS, e.g. approx. 50 μS or approx. 30 μS. By preparing water, e.g. with the assumed GH = 5, we can obtain the specific conductivity H of 200, 250 or 150 μS. Conversely, looking only at the conductivity, during water preparation, we will get water not necessarily with the assumed GH. In a short time, we are planning an article where we will try to explain the issues just raised using specific examples of mineralizers.
