About this product

Makes it possible to introduce fish immediately after setting up a new aquarium. The live bacteria contained within Tetra SafeStart instantly creates a biologically active habitat.

New aquarium filters lack the beneficial bacteria that remove harmful ammonia and nitrite. If the aquarium is stocked too rapidly, this can lead to New Tank Syndrome, with fish being harmed by high levels of pollutants. To avoid this, traditionally it has been recommended to stock the aquarium slowly over a period of many weeks.

Recent advances in technology have led to the development of Tetra SafeStart, a unique blend of bacteria responsible for ammonia and nitrite removal in aquariums - Nitrospira, Nitrosospira, and Nitrosomonas. These bacteria are included in high concentrations in Tetra SafeStart, and when added to a new aquarium quickly establish the biological activity of the filter. This allows fish to be added safely to a new aquarium, without the risk of dangerous rises in ammonia and nitrite.

  • Enables safe introduction of fish to new aquariums
  • Immediate activation of aquarium's biological activity
  • Reduces dangerous ammonia and nitrite levels, thereby helping to keep fish healthy
  • Also ideal for maintaining biological activity following water changes, filter maintenance, power cuts etc
  • Can be used to resolve problems with high ammonia or nitrite in both new and established aquariums


When setting up a new aquarium: Set the aquarium up and turn on all equipment, using Tetra AquaSafe to condition the water. Wait at least 24hrs to ensure that the equipment is working correctly, and to allow the aquarium to reach the correct temperature. Then add 5ml of SafeStart per 6 litres of water, at the same time as adding the fish. We recommend adding a moderate number of fish. As a precaution, in the two weeks following the introduction of the fish, we recommend regularly testing the ammonia and nitrite level using TetraTest kits. If levels rise, perform a partial water change using Tetra AquaSafe to reduce them.

Following filter maintenance, water quality problems, or water changes: Add 5ml of Tetra SafeStart per 6 litres of water.

If storing Tetra SafeStart, keep between 10°C & 30°C. Aquarium water must be 20°C (room temperature) or above.
