Is Tetra FilterActive safe for all of my fish?
Yes, this product is safe for all aquarium inhabitants – fish, plants and invertebrates – and can be used with total peace of mind. It is 100% biological and designed for use in freshwater aquariums. Even if you use too much, you don’t need to worry (see next question).
What happens if I put too much Tetra FilterActive in my aquarium?
The product is 100% biological. Aside from increased oxygen consumption (caused by the bacteria), excessive amounts have no negative effects. The “excess” bacteria do their work for as long as the conditions allow and then die, leaving behind a stable bacteria population to maintain a biological balance. If you use too much, you should ensure a sufficient oxygen supply, for example using a diaphragm pump.
Can I use Tetra FilterActive in my marine aquarium?
No, Tetra FilterActive is only suitable for freshwater aquariums.
Can I use the product 2–3 days after cleaning the filter?
Yes. However, with its live, highly effective bacteria, the product is designed to immediately support biological activity, which will decrease due to the loss of bacteria. Ideally, it should be used shortly after care activities (such as cleaning the filter, removing sludge/cleaning the substrate or changing the water) that remove helpful bacteria unintentionally.
What is the shelf life of Tetra FilterActive?
It can be kept for at least 18 months without refrigeration at temperatures between 2°C and 30°C.
What is the difference between Tetra SafeStart and Tetra FilterActive?
Tetra SafeStart is a “quick starter” product for a new aquarium. It is used when setting up an aquarium to quickly establish biological activity and to significantly reduce the normal settling-in phase. Its live, nitrifying bacteria break down ammonia and nitrite (which are toxic for fish) and allow fish to be introduced to the new aquarium at an earlier point.
Tetra FilterActive also provides these live, nitrifying bacteria. But its new 2in1 formula also contains sediment-reducing cleaning bacteria. The new formula reduces cleaning effort because sediment does not need to be removed from the filter as often. Tetra FilterActive also replenishes the nitrifiers lost after cleaning the filter, changing the water or medical treatment and re-establishes biological activity in the aquarium. Tetra FilterActive can also be used when new fish are added to the aquarium to prevent potential fluctuations in the biological balance. The new 2in1 formula can also be used if high stocking density leads to a build-up of sludge and sediment. In this case, weekly use is recommended.
