Fine-Grain Aquasoil Substrate (9L)

Fine-grain aquasoil in the 9-litre format provides enough substrate to fully floor a standard 90-litre aquarium at a 5 cm depth, making it the go-to choice for serious planted tank hobbyists. The fine particles create a dense growing medium that plant roots penetrate quickly, and the high cation exchange capacity locks nutrients tightly in the substrate matrix for gradual release over many months.

The substrate actively buffers pH toward the slightly acidic range ideal for CO2-injected high-tech tanks and soft-water species. Initial cloudiness resolves within 24–48 hours of filling. The 9-litre volume also supports larger aquascape compositions where visual texture consistency across the full tank floor is important.
