GH and KH in the Aquarium
Aquarists seek to provide a healthy aquarium environment by duplicating the water conditions of the natural habitats of their fish. Tap water rarely provides the water conditions necessary to maintain an optimal aquarium. Some tap water supplies have a very low KH level (below 3 °dKH). This type of water has very little pH buffering capacity and can contribute to wide pH swings in the aquarium. When water evaporates from the aquarium, it leaves behind hardness ions. Topping off with tap water simply adds more minerals to the aquarium, resulting in a steady increase in GH. It is therefore necessary to test the GH and KH frequently to monitor water quality and prevent stressful conditions from occurring. Use the table below to create the ideal water hardness levels for your aquarium fish. When keeping a community aquarium with a variety of tropical fish, adjust the GH and KH to 3° - 6° (50 - 100 ppm).

Dennerle CO2 Night Cut-off Valve Comfort
For magnificent plant growth, DENNERLE recommends a CO2 content in the aquarium of approx. 20 mg/l.
As certain correlations apply between CO2 content, carbonate hardness (CH) and pH value, the CO2 content in the water can be calculated according to a simple procedure:
Measure the carbonate hardness of your aquarium water.
Read the pH value which corresponds to the desired CO2 content from the table. You should set this pH value +/- 0.1 by adjusting the number of bubbles accordingly. Example: Carbonate hardness 4 °d, recommended pH 6.8 +/- 0.1.
The procedure is even simpler with the DENNERLE CO2 long-term test Correct + pH.
$18.00Dymax Base Soil series decreases the hardness of the water and lower the pH level to the degree at which most aquatic plants can consume nutrients and comfortably grow. The soil granules maintain the shape and density underwater security good circulation of water oxygen through the substrate. With Dymax Base Soil, growing difficult plants become easier and it is ideal for fishes demanding soft water.
