Hydrocarbonate 5 L Bucket/8 kg Coarse Aqua Medic

Coarse Hydrocarbonate Aqua Medic – 5 L / 8 kg Bucket (grain size 6–8 mm)

The Coarse Hydrocarbonate Aqua Medic is a pure natural substrate made from calcium carbonate, specially designed for biological filters and as bottom substrate in marine aquariums and African tanks such as Malawi and Tanganyika. With its coarse grain size of 6 to 8 mm, it offers an optimal surface for bacterial colonization and effective mechanical filtration.

Recommended Applications

This substrate is ideal for:

• Biological filters requiring an extensive bacterial colonization surface.
• Mechanical filters for effective particle retention.
• As a bottom substrate in marine aquariums and African tanks (Malawi, Tanganyika).

Advantages

• Maintains a stable alkaline pH, essential for the health of fish and corals.
• Creates a natural calcium/carbonic acid balance in the aquarium.
• Promotes effective biological filtration thanks to its porous surface.

Technical Characteristics

• Grain size: coarse (6–8 mm)
• Volume: 5 liters
• Weight: 8 kg
• Composition: pure natural calcium carbonate

Usage Tips

For optimal efficiency, lightly rinse the substrate before use to remove fine particles. Replace the substrate according to the specific needs of your system, depending on the biological load and pH stability.
