Hygger CO2 Aquarium Soil, 2 kg Planted Tank Substrate for Plants and Shrimp

Hygger CO2 Aquarium Soil is a 4.4 lb (2 kg) planted-tank substrate designed to support aquatic plants and shrimp while buffering aquarium water to a pH of 6.5–7.5.

• Buffers water to pH 6.5–7.5 — helps maintain conditions for aquatic plants and sensitive shrimp.
• Porous sintered soil — provides a structure where beneficial bacteria can colonize.
• Fine-textured substrate that is not easy to scatter — helps keep soil in place in an aquascape.
• Naturally softens water and reduces hardness — supports a planted-aquarium environment.
• Use without rinsing — avoids washing away beneficial microorganisms or breaking the soil down into mud.

Setting up a planted aquarium means choosing a substrate that supports plant growth and suits the water conditions your tank needs. Hygger CO2 soil is made for aquascaping with aquatic plants and shrimp, and can also be used in aquariums with fish. Its water-buffering action and porous structure make it a substrate choice for both planting and beneficial-bacteria colonization.

What does Hygger CO2 Aquarium Soil do for aquarium water?

It naturally acidifies and softens water while buffering it to a slightly acidic pH range of 6.5–7.5. The soil is formulated to help keep pH stable for sensitive shrimp and aquatic plants, while reducing water hardness. Its porous, sintered structure supports the colonization of beneficial bacteria, contributing to a stable water environment.

• Designed for planted aquariums and professional aquascaping.
• Creates a nutrient-rich environment for aquatic plants.

How do I add the soil and prepare the tank?

Pour Hygger CO2 Aquarium Soil directly into the tank without rinsing it, then add water slowly. Rinsing can remove beneficial microorganisms and may cause the soil to break down into mud. After setup, perform daily water changes for the first 3–5 days, with at least three water changes before adding livestock.

• Allow for the initial nutrient release before introducing sensitive livestock.
• Do not add the soil directly to an established aquarium; initial release may temporarily affect sensitive species.

Is this aquarium substrate suited to my tank?

Hygger CO2 Aquarium Soil is intended for planted aquariums with aquatic plants, shrimp, and fish. Its fine texture is not easy to scatter, making it suitable for arranging substrate as part of an aquascape. The 4.4 lb (2 kg) quantity is the package size; choose the amount based on your aquarium setup.

• Made for freshwater aquascaping and planted-tank use.
• Supports tropical shrimp and aquatic plants through its buffered water conditions.

This soil suits aquarists building a planted layout who want a substrate that supports plant growth, beneficial-bacteria colonization, and softened, buffered water. It is intended for a new setup rather than direct addition to an established tank, and the soil is used without rinsing.
