Tac

Also called KH (Karbonathärt in German). The complete alkalimetric title (or temporary hardness, or carbonated hardness) indicates the content of water in carbonates and calcium and magnesium bicarbonates (precipitating salts on the boil).

The term "TAC" is an acronym that can have several meanings in different contexts, but in the field of aquarophilia, it is most often used to designate the "total carbonate alkalinities".

In an aquarium, the TAC corresponds to the amount of carbonates and bicarbonates present in the water. It is measured in "degrees of Germany" (DKH) or "degrees of French" (DGH). We speak of "degree of Germany" when we use a measurement scale ranging from 0 to 14, and "degree of French" when using a scale ranging from 0 to 18.

The TAC is important in the aquariophilia because it plays a key role in maintaining the balance of the parameters of the water in your aquarium. Indeed, the TAC intervenes in the regulation of the pH of the water. A pH too high or too low can be harmful for fish and other inhabitants of the aquarium.

The TAC can be influenced by several factors, such as the quality of your tap water, the materials used in the construction of the aquarium and its accessories (such as substrate, stones and plants), as well as the Chemicals you use (such as treatment against parasites or water holding products).

It is recommended to regularly measure the tac of your aquarium to ensure that it is in an optimal values ​​range for the species you host. If you find that the TAC is too high or too low, you can use specific products to correct it, such as buffers to increase the TAC or acids to decrease it.

It is also important to take into account the hardness of the water from your aquarium when you measure the TAC. The hardness of the water corresponds to the amount of minerals dissolved in water, such as calcium and magnesium. The hardness of the water can also influence the pH and the tac of the aquarium.

In summary, the TAC is an important parameter of the water of your aquarium which plays a key role in maintaining the balance of water and the health of its inhabitants. It is recommended to measure it regularly and take the necessary measures to keep it in an optimal values ​​range for the species you host. This may require the use of products such as buffers or acids, depending on the situation. It is also important to take into account the hardness of the water from your aquarium when you measure the TAC and to ensure that the hardness of the water is suitable for the species that you host. In general, it is recommended to carefully follow the parameters of your aquarium water and to react quickly if you see changes in order to maintain a healthy and balanced environment for the inhabitants of your aquarium.
