A dry, pest-free rock, ready for sowing

Free of any parasitic life, this rock is perfectly healthy upon introduction . It contains no cyanobacteria, unwanted worms, or invasive algae.

This promotes natural, efficient, and long-lasting biological filtration, reducing the need for complex filters. This porosity also makes it lighter than it looks, making it easier to handle and stack when arranging decor.
