Hygger CO2 Aquarium Soil for Planted Tanks, 6 kg No-Rinse Substrate

Hygger CO2 aquarium soil is a planted-tank substrate for aquatic plants and shrimp, supplied in a 13.2 lb (5.99 kg) amount.

• Supports a pH range of 6.5–7.5 — helps create suitable water conditions for aquatic plants and shrimp.
• Porous, sintered soil structure — provides surfaces for beneficial bacteria to colonize.
• Naturally acidifies and softens water — supports conditions for planted aquariums.
• Fine-textured soil that is not easy to scatter — helps keep substrate in place.
• Designed for direct use without rinsing — avoids washing away beneficial microorganisms or breaking the soil down into mud.

Choosing a substrate is part of setting up a planted aquarium: it affects the conditions around plant roots and contributes to the water environment. Hygger CO2 aquarium soil is intended for aquascapes with aquatic plants and shrimp, with a porous structure and water-buffering properties suited to that use. Plan the initial setup before adding livestock, since the soil can release nutrients at first.

What water conditions does this aquarium soil support?

Hygger CO2 aquarium soil is formulated to maintain a stable pH of 6.5–7.5. It also naturally buffers water toward a slightly acidic pH and reduces hardness, while its porous sintered structure supports beneficial bacteria colonization. These properties make it a substrate option for planted aquariums where water conditions matter to plants and shrimp.

• Its water-buffering action is designed for planted-tank use.
• The porous structure supports the establishment of beneficial bacteria.

How should I prepare the tank before adding fish or shrimp?

Use Hygger CO2 aquarium soil in a new setup and allow for water changes before introducing livestock. Nutrient release during the initial setup may temporarily affect sensitive species, so avoid adding the soil directly to an established tank. Make daily water changes during the first 3–5 days after setup, with at least three changes before adding livestock.

• Allow the initial setup period before introducing fish or shrimp.
• Keep the initial nutrient release in mind when planning livestock introduction.

Does the soil need to be rinsed before use?

No. Pour Hygger CO2 aquarium soil directly into the tank without washing it, then add water slowly. Rinsing can remove beneficial microorganisms and may cause the soil to break down into mud, making the water dirtier.

• Pour the soil directly into the aquarium.
• Add water slowly during setup.

This substrate suits aquascapers setting up a planted aquarium with shrimp or other livestock after the initial water-change period. Its fine texture, porous structure and water-buffering properties make Hygger CO2 aquarium soil a practical choice for a new planted-tank setup, rather than a soil to rinse or add directly to an established aquarium.
