Tetra FilterActive contains a mix of living starter and cleaning bacteria to help reducing sludge and crud on the ground be it gravel, sand or soil. This helps to compensate for bacterial losses caused by cleaning the aquarium. The living starter bacteria contained keep the filter biologically active. In addition, the filter can be kept clean longer in a natural way by the mulm-degrading cleaning bacteria. This increases the performance of the filter and extends the cleaning interval.


  • Contains live starter bacteria and crud-degrading purification bacteria.
  • Degrades ammonia, nitrite, organic contaminants such as fish excrement, crud accumulation, food and plant residues
  • Reduces filter sludge, extends the cleaning interval and increases the performance of the filter
  • Promotes the bioactivity of the substrate, prevents decay and reduces maintenance effort
  • Broad spectrum of bacteria activity, to maintain biological activity after water changes and filter cleaning


Shake well before use. After changing or cleaning the filter, add 5 ml to 20 l aquarium water. 1 line on the measuring scale = 10 ml. Half the dosage after water changes.
