The APT s/Start from 2HR Aquarist supports a successful start of a new aquarium. This all-in-one booster consists of two different components. It stimulates the natural cycle of microorganisms and accelerates the start-up phase. One component is added directly to the substrate and increases the nutrient value of the substrate and accelerates the root formation of the aquatic plants. A second component (blue bag) is added to the water. The bacteria it contains promote a biological balance.
APT START provides the plants with ammonia nitrogen and a number of important minerals for good plant growth.


  • Soil enrichment and bacterial starter in one
  • Consisting of two different components
  • Supports the growth of aquatic plants
  • The contents are sufficient for a floor area of 60 x 30 cm


Spread the contents of the bag evenly over the substrate. 1 bag (45g) is enough for an area of 60 x 30 cm. After filling, add the second, blue bag directly into the water.
