UNS Controsoil 1L Normal Brown is a planted aquarium substrate created to support vigorous aquatic plant growth while maintaining stable water conditions. This blend of natural soil and volcanic ash is formulated to emphasize impurity uptake and water balance from the initial setup, making it suitable for a wide range of aquascaping styles and experience levels.

Unlike heavily enriched substrates that may trigger elevated ammonia levels, this substrate is designed to keep nutrient release modest, helping to reduce sudden parameter swings in freshwater systems. Its structure offers reliable root support and a clean aesthetic that complements both minimal and densely planted layouts.

Controsoil is produced in multiple grain sizes and color options, allowing aquarists to match the substrate to specific plant types, livestock, and visual preferences.

Key features

• Ready to use out of the bag, with no pre-rinsing typically needed
• Formulated for minimal ammonia output during initial use
• Provides gentle pH & kH buffering to support stable water chemistry
• Appropriate for tropical fish and freshwater shrimp displays
• Intended for freshwater and planted aquarium environments
• Offered in two color choices and three distinct grain sizes

Bag size

1L Normal Brown is a suitable volume for compact aquariums such as the UNS 20C cube, depending on desired substrate depth and layout style.

Grain size details

Normal granules measure approximately 5 mm (0.2 in), providing a coarser texture that benefits robust, deep-rooted aquatic plants such as Echinodorus species and performs especially well in medium to larger aquariums where structure and stability are important.
