kH+Ca 1 is a solution designed to quickly increase the carbonate hardness of water and stabilize the pH buffer in reef aquariums. It is part of the basic supply system kH+Ca by Grotech.
Carbonate hardness plays an essential role in pH stability. A kH value that is too low poses a risk to the aquarium and can lead to a drop in pH. The ideal kH value is around 10 °kH.
This solution allows for a quick correction of a drop in kH and supports the buffering capacity of the water.
The addition of 50 ml of kH+Ca 1 increases the carbonate hardness by 2 °kH for 100 L of aquarium water.
The dosage should be adjusted to the actual volume of the aquarium and the measured needs.
Do not mix in a graduated cup.
