JBL’s Manado gravel is a clay-based substrate specifically engineered for use in freshwater and planted aquariums. Manado gravel possesses inert and porous qualities, with its primary advantage lying in its capacity to effectively absorb surplus fertilizers and nutrients from the water column. These absorbed nutrients are retained within the gravel layer, providing an essential resource for the nourishment of plant roots. This advantageous feature not only reduces the potential for undesired algae proliferation but also ensures a greater nutrient supply available for your aquatic plants.

  • 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
