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. To start your cycle, simply seed with a good bacterial supplement , such as Microbe-Lift Special Blend . After 4 to 6 weeks of maturation, it is ready to welcome your first inhabitants. Rinsing with tap water is recommended before installation.
A porous surface that boosts biological filtration
Its highly aerated internal texture provides a huge surface area for nitrifying and denitrifying bacteria . 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.
