Tetra FilterActive 100ml, 250ml

Tetra FilterAcive is a bacterial preparation that supplies the filter with highly active living bacteria and supports the biological activity in the freshwater aquarium.

The water is not clarified mechanically by a filter system alone. Special bacteria are required for the conversion of ammonia to nitrate, which finds a large space in a sufficiently dimensioned filter system. With the use of Tetra SafeStart, the aquarist creates optimal conditions for good bioactivity in the aquarium. A widespread opinion that predominantly the bacteria of the Nitrobacter group are active as nitrifying bacteria in the aquarium has been scientifically refuted. In natural biofilms from aquariums, Tetra Research was able to identify the bacteria of the Nitrospira strain as the predominant representative of the nitrite-reducing bacteria. The ammonia, which is also very harmful to the fish, is broken down by bacteria of the genera Nitrospira and Nitrosomonas. The latest discoveries in microbiology ultimately led to SafeStart's product development. Optimal conditions for the settlement of these important bacteria are achieved with Tetra Bactozyme. It covers all surfaces with a bacteria-promoting biofilm on which nitrifying bacteria can develop. Tetra Biocoryn complements these products.

Tetra FilterActive adds active living bacteria and thus supports the permanent biological activity in the aquarium. The breakdown of pollutants such as ammonia and nitrite is accelerated. The cleaning performance of the filter for clear water is improved and the biological balance in the aquarium is maintained. Tetra FilterActive promotes good water values and the well-being of fish and increases filtering after filter maintenance or water changes.

Application
Shake well before use. After filter cleaning or change, add 5 ml to 20 litres of aquarium water. Dose directly into the filter. Half dosage after water changes.

Tetra FilterActive replaces highly active, useful bacteria that are lost during filter cleaning or water changes, so that good water quality and the well-being of the fish are maintained!
