APT e/Estimative Index from 2HR Aquarist is a fertiliser for particularly heavily planted aquariums. Aquascapes with very lush greenery, such as Dutch Style Aquascape, are particularly dependent on intensive fertilisation. In order to meet the requirements of all aquatic plants, the amount of nutrients available is usually not sufficient. If many aquatic plants are to grow well in an aquascape, it is important to ensure a sufficient supply of nutrients.
APT e/Estimative Index ensures a sufficient supply of nitrogen, phosphorus, potassium, iron, magnesium and essential trace elements. This ensures the vitality and growth of the aquatic plants and allows the aquascape to show its most beautiful side. 2HR Aquarist provides the fertiliser in two different packaging sizes.
