My Latest Discoveries


Today I bought a test kit for my project. It will test for pH and Chlorine.



I also found out about the normal requirements for water. Take a look at them.

Iron: Too much iron may stain things. The normal amount is 0.3mg to 1ppm).

Hardness: For water to be moderately hard, it needs to have 3.5 grains to 7 grains of hardness.

Copper: The more copper makes water worse. The normal amount is 1.3ppm.

Chlorine: It is good to have 0.1 to 4mg, because it reduces bacteria growth.

pH: pH measures acid and alkalinity. A pH of 7 is neutral.
