Ultum Nature Systems Controsoil

Ultum Nature Systems Controsoil is a fine, black volcanic ash freshwater aquarium substrate designed for live plant propagation and aquascaping, with pH and kH buffering and a 1-liter quantity.

• Fine black volcanic ash substrate, 1 liter — gives freshwater aquariums a dedicated base for planted layouts.
• Granule composition and sizes support oxygen exchange and provide rich nutrients for aquatic plants.
• Buffers toward slightly acidic water, with 6.8 pH and lower kH — helps create conditions for aquatic plant nutrient consumption.
• No rinsing required; absorbs impurities — helps clarify and detoxify cloudy water.
• Low ammonia release — promotes and accelerates beneficial bacteria growth.
• Designed for freshwater fish and shrimp that prefer slightly acidic water.

Controsoil is made for freshwater setups where the substrate needs to support planted layouts as well as aquatic inhabitants suited to slightly acidic conditions. Its stated uses include live plant propagation and aquascaping, making it relevant for building a planted aquarium rather than choosing a substrate without a plant-focused role.

How does Controsoil support planted aquarium water conditions?

Controsoil buffers water toward a slightly acidic pH and lowers total water hardness, or kH. The product’s 6.8 pH designation and buffering function are intended to create an environment for better aquatic plant nutrient consumption. Its granule composition and sizes are also designed to support oxygen exchange around the substrate and supply rich nutrients for aquatic plants.

• Use it as the substrate in a freshwater planted aquarium.
• Its stated plant uses include propagation and aquascaping.

Can Controsoil be used with fish and shrimp?

Yes. Controsoil is suitable for freshwater inhabitants, including tropical fish and shrimp, when they prefer slightly acidic aquarium water. This makes it a substrate option for planted freshwater environments shared with those inhabitants, rather than a product intended for every type of aquarium setup.

• Compatibility is stated for freshwater fish and shrimp.
• The relevant water preference is slightly acidic.

Does Controsoil need rinsing before use?

No rinsing is required. Controsoil absorbs impurities to help clarify and detoxify cloudy water, while its low ammonia release promotes and accelerates beneficial bacteria growth. These properties are part of how the substrate is designed to support a freshwater aquarium as it is established.

• The substrate is fine grade and black in color.
• The material is volcanic ash.

Controsoil is suited to aquarium keepers creating a freshwater planted layout, propagating aquatic plants, or aquascaping with fish or shrimp that prefer slightly acidic conditions. Its 1-liter quantity, fine black volcanic ash substrate, and water-buffering function make it a plant-focused choice for those specific freshwater setups.
