Aquarium Sand Gravel 2kg

Biological Filtration: The porous surfaces of gravel provide immense surface area for beneficial nitrifying bacteria to colonize, keeping ammonia and nitrite levels safely in check.

Heavy Root Support: Gravel is excellent for anchoring live aquarium plants. Its weight holds down root systems firmly while still allowing water to reach the roots.

Superior Water Flow: The larger gaps between gravel pieces allow for better water circulation and oxygen exchange down into the substrate, which helps prevent harmful toxic gas pockets.

Surface Cleaning: Because the particles are so tight, fish waste and uneaten food stay on the surface rather than sinking between pieces, making it visually obvious and easy to clean off.

Natural Behavior: It allows fish to exhibit natural sifting and burying behaviors without scraping their mouths or gills.
