UNS Controsoil Fine Black 3L Aquarium Substrate provides a stable base for planted aquariums, supporting healthy root development and long-term balance. This substrate is a natural combination of soil and volcanic ash, formulated to absorb impurities while maintaining consistent water conditions.

Key features include:

• No rinsing required, reducing setup time and minimizing cloudy water
• Controlled ammonia release to encourage beneficial bacteria growth during the cycling process
• pH and kH buffering, stabilizing water to a slightly acidic level and lowering hardness for improved nutrient uptake
• Safe for freshwater species such as tropical fish and shrimp that thrive in mildly acidic environments
• Granule size and composition designed to promote oxygen exchange for aquatic plants

Volume and tank size guidance:

• 1 L (0.26 gal) – suitable for tanks up to 2 gal (7.6 L)
• 3 L (0.79 gal) – suitable for tanks up to 9 gal (34 L)
• 10 L (2.64 gal) – suitable for tanks up to 20 gal (76 L)

Independent testing compared UNS Controsoil with another freshwater substrate over a two-week period using RODI water without water changes. Results showed that Controsoil maintained stable conditions, with minimal ammonia release and a gradual stabilization of pH to approximately 6.8. This environment supports tropical fish, freshwater shrimp, and aquatic plants, while encouraging long-term aquarium stability.
