Hydrocarbonate 15 L Bucket/21 kg Coarse Aqua Medic

Coarse Hydrocarbonat Aqua Medic – 15 L / 21 kg Bucket (Grain Size 12–15 mm)

The Coarse Hydrocarbonat Aqua Medic is a pure natural substrate made of calcium carbonate, specifically designed for biological filters and as a substrate base in marine aquariums and African tanks such as Malawi and Tanganyika. With its coarse grain size of 12 to 15 mm, it offers an optimal surface for bacterial colonization and efficient 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 substrate base 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 efficient biological filtration thanks to its porous surface.

Technical Specifications

• Grain size: coarse (12–15 mm)
• Volume: 15 liters
• Weight: 21 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, based on biological load and pH stability.
