Features Active substrate Grain size of 2 - 3 mm Provides good growth Can be used without any other types of bottom layer Stimulates the development of reddish nuances Contains varying amount of Silicates - Natural product Description The Tropica Aquarium Soil is burned from valuable clays and ensures good and active growth of the plants right from the beginning. The positive nutrient balance has a particularly beneficial effect on the development of reddish nuances in the plants. Tropica Aquarium Soil is a complete substrate that can be used without any further supplements. In addition, this Soil is an active substrate that slightly lowers the pH and has a weak influence on the chemistry of the water. It is therefore also ideally suited for shrimp tanks. As this is a natural product, it may contain varying amounts of silicates. It is recommended to perform at least two water changes per week during the first three weeks after the aquarium has been newly set up.
