Complete alkalimetric title

See T.A.C.

The complete alkalimetric title (TAC) is an indicator of the concentration of hydrogen ions (H+) in water. This concentration is measured on a logarithmic scale of pH, which goes from 0 to 14. A pH 7, the water is considered to be neutral. Everything below 7 is considered to be acidic, while everything that is above 7 is considered to be alkaline.

The TAC measures the total quantity of alkaline substances (that is to say capable of neutralizing acid) present in water. These substances can be hydroxyl ions (OH-), bicarbonate ions (HCO3-), carbonate ions (CO32-), hydrogen ions (H+) or amine ions (NH3+).

The TAC is important for aquariophiles because it can influence the well-being and health of fish. Indeed, each species of fish has specific TAC requirements and which depend on their natural habitat. If the aquarium water tac is too high or too low compared to the needs of the species, this can cause health problems such as digestive disorders, respiratory infections or reproductive problems.

It is therefore important to regularly monitor the aquarium TAC and maintain it within the recommended limits for the fish species you maintain. To do this, you can use a commercial TAC tester. There are also chemicals that you can add to the water to increase or decrease your TAC, depending on your needs. However, it is recommended to do this carefully and follow the manufacturer's instructions so as not to disturb the balance of the aquarium.

It is also important to take into account the impact of the TAC on plants and other residents of the aquarium. Certain species of plants and invertebrates have requirements in terms of TAC which differ from those of fish, it is therefore important to choose the species that best suit your aquarium taking into account your TAC.

In summary, the TAC is an indicator of the concentration of hydrogen ions in water which can have an impact on the well-being and health of fish, plants and other inhabitants of the aquarium. It is important to occur regularly to monitor the aquarium TAC and to maintain it within the recommended limits for the fish species that you maintain. To do this, you can use a commercial TAC tester. There are also chemicals that you can add to the water to increase or decrease your TAC, depending on your needs. However, it is recommended to do this carefully and follow the manufacturer's instructions so as not to disturb the balance of the aquarium.
