Hygger CO2 Aquarium Soil for Plants and Shrimp, 4 kg, pH-Buffering Substrate

Hygger CO2 aquarium soil is a planted-tank substrate for aquatic plants and shrimp, with a buffered pH range of 6.5–7.5 and an 8.8-pound (3.99 kg) quantity.

• Buffered pH of 6.5–7.5 — supports conditions suited to aquatic plants and sensitive shrimp.
• Porous, sintered soil — gives beneficial bacteria a structure to colonize.
• Fine-textured substrate — is less likely to scatter around the aquarium.
• Naturally acidifies and softens water — helps create conditions for planted aquariums.
• Use without rinsing — preserves beneficial microorganisms in the soil.

Setting up a planted aquarium means choosing a substrate that supports plant growth while helping establish suitable water conditions. Hygger CO2 aquarium soil is made for aquascaping with aquatic plants and shrimp. It can be used in a new aquarium; during initial setup, its nutrient release may temporarily affect sensitive species, so plan the water changes before adding livestock.

How does Hygger CO2 soil support planted aquariums?

Its porous, sintered structure encourages beneficial bacteria to colonize the substrate, while its fine texture helps keep the soil from scattering easily. The soil also naturally reduces water hardness as it acidifies and softens the water, contributing to a nutrient-rich environment for aquatic plants.

• Designed for aquascaping and planted aquariums.
• Made for use with aquatic plants and shrimp.

What water conditions does this aquarium soil create?

Hygger CO2 soil is formulated to maintain a stable pH between 6.5 and 7.5. This range is intended to support aquatic plants and sensitive shrimp in planted tanks, while the soil’s natural water-buffering action helps maintain slightly acidic conditions.

• Made for planted aquariums with tropical shrimp.
• The pH range is 6.5–7.5.

How should I prepare and add the soil?

Pour the soil directly into the aquarium without rinsing it, then add water slowly. Washing can remove beneficial microorganisms and may break the soil down into mud. After setup, make daily water changes during the first 3–5 days, with at least three changes before adding livestock. Avoid adding it directly to an established tank because the initial nutrient release may temporarily affect sensitive species.

• Add water slowly after placing the soil.
• Complete at least three water changes before introducing livestock.

Hygger CO2 aquarium soil suits aquascapers setting up planted tanks who want a substrate designed for aquatic plants and shrimp, with a porous structure for bacterial colonization and natural water conditioning. It is intended for aquarium setup rather than direct addition to an established tank.
