ADA Pack Checker TH (Total Hardness) test
ADA Pack Checker TH (Total Hardness) can the sum of some dissolved in the water cations to be measured, such as calcium ions. When the total hardness of the aquarium water is too high, the color of newly formed leaves and the vegetation disturbed.
Too much calcium ions in the water to disrupt the growth of plants and prevent the nutrients can assimilate. When the hardness is too high, it is advisable to to soften water. For example, with a softinizer or reverse Osmosis device.

Measurement of the GH (Joint Hardness) of the aquarium water:
The GH gives the total hardness of the water. That is to say, the total amount of salts and minerals that there. The most tropical fish and plants that prefer soft water. To the hardness of the water to decrease, with osmosis water or rain water to be refreshed. In aquarium water with a high hardness, and where a lot of lime in it, is resolved, is less free to absorb CO2 is present. In water with a high hardness should be in proportion more CO2 to be added. The harder the water is, the more difficult it is to get the pH down to get.
We recommend for a planted aquarium with a hardness between 6° and 8° GH.
