Natural substrate for freshwater aquariums.
Key Features:
• Optimal plant care through porous structure and nutrient storage function: substrate for freshwater aquariums.
• Vigorous plant growth, prevents algae: effective settlement of beneficial soil bacteria and ideal root growth thanks to natural pore structure. Support for the filter. Crystal-clear water.
• Ideal for fish, invertebrates and plants: no unwanted pollutants released into the water. Round-shaped granule grains are gentle on sensitive barbels of bottom-dwellers.
• High storage capacity: the natural substrate absorbs the surplus nutrients and releases them when required.
