Ultum Nature Systems Controsoil is a finely textured, black freshwater aqua soil substrate designed for planted aquariums

It provides a foundation for healthy roots, vibrant plant life, and visually striking aquascapes

Built from volcanic ash and mineral-rich components, the granules are sized to promote steady oxygen exchange around roots while delivering nutrients over time, helping roots establish and plants thrive in a balanced environment

Designed for planted aquariums Granule composition and varied sizes support gentle oxygen exchange and steady nutrient availability for aquatic plants

Suitable for freshwater inhabitants that prefer slightly acidic water, helping create a stable, plant-friendly baseline

Low ammonia release may contribute to a healthier starting microbiology, reducing quick spikes as the tank cycles

No rinsing required, with the substrate actively absorbing impurities to help clarify cloudy water as it settles

Packing includes pH and KH buffering, helping maintain a slightly acidic environment and softened hardness for plant nutrient uptake

In practical aquascapes In tanks, the dark, fine granules blend with decorations and greens, providing a strong contrast that makes plant colors pop

Roots tend to anchor more readily in a uniform base, while the substrate’s composition can contribute to calmer water parameters when paired with proper filtration

For communities that include shrimp or tropical fish, Controsoil aims to support a core substrate that complements plant growth and helps manage bioload

Results depend on overall tank management, water changes, and filtration, not on the substrate alone

Tips for results Spread Controsoil evenly to your desired depth to form a stable rooting base

Layer with decorative gravels or hardscape to showcase the substrate’s deep-black color

Fill the tank slowly to minimize clouding and allow the substrate to settle gradually

FAQ Q: What makes Controsoil suitable for planted freshwater aquariums

A: Volcanic ash substrate with pH buffering and low ammonia release supports plant rooting and steadier water parameters

Q: How should Controsoil be used in an aquarium

A: Spread evenly to your desired depth, no rinsing required, fill slowly to minimize clouding, then add plants and livestock
