Stone aquarium decoration

These aragonite stones are naturally porous and perforated for a natural appearance and active participation in biological filtration. The porous surface allows the installation of denitrifying bacteria essential to the balance of a reef tank. Each stone is unique and can be used to create original structures in the s, as well as being an ideal support for corals. It's an ecological alternative to live stone, which is removed from its natural environment, disrupting its ecosystem. The stones have already been pre-rinsed to limit sediment residues, and are biofilm-free.
