Description

Black Venom Gravel from the WIO Gravels series is a natural gravel with a dark grey colour. When wet, it appears significantly darker and features accents ranging from anthracite to black.
The dark grey, smooth surfaces of these river pebbles create a harmonious contrast with plants and hardscape. The grain sizes of Black Venom Gravel can be ideally combined with other WIO Stone and Nano Stone varieties.

Note

All WIO gravels are pre-washed. However, the manufacturer recommends briefly rinsing the gravel with cold water before use to remove transport-related abrasion. This also helps prevent sand particles from floating up when filling the aquarium.

Product Safety

Caution: risk of swallowing

Warnings:

Dust may temporarily irritate eyes and skin. Avoid contact and rinse with water if necessary.
Inhalation of dust may irritate the respiratory tract. Ensure adequate ventilation.
Small amounts may be swallowed by children or pets. This is not a toy. Keep out of reach.
Risk of slipping if material is spilled. Clean up immediately.

General information:

Handling dry material may generate dust. Rinse thoroughly before use and add slowly to the aquarium. Fine filtration helps to clear turbidity.
Calcareous variants may increase pH and KH values. Suitable for hard water such as in Malawi or Tanganyika aquariums, as well as brackish or marine setups. pH-neutral variants are suitable for softer biotopes. Monitor water parameters regularly.
Thick substrate layers may accumulate detritus. Shape the substrate with a slight slope, siphon carefully and avoid strong disturbances.
Colour and texture variations are batch-dependent and may vary slightly depending on lighting.
Store dry and airtight to prevent dust and moisture absorption. Keep away from food, children and pets. Transfer safely if packaging is damaged.

Handling instructions:

Preparation: Rinse thoroughly in a clean bucket until the water is mostly clear.
Distribution: Spread evenly. Do not compact the substrate too much in the aquarium. Shape with slopes for water flow.
Filling with water: Place a plate or plastic sheet on the substrate. Pour water slowly over it to avoid disturbance.
Start-up phase: Run the filter continuously. Partial water changes help remove fine particles.
Chemical selection: Use pH-neutral substrate for soft or neutral water. Choose calcareous variants for alkaline water. Monitor water parameters regularly during the first weeks.
Ongoing care: Siphon carefully and avoid stirring up dust.
