USE & PLACEMENT

RINSE: Rinse thoroughly until the water runs clear before use.
FILTER USE: Place in a canister, HOB or internal filter, sump, pond filter, media bag or filter basket where water can pass through it.
FLOW: Keep the media in a high-flow area and do not pack it tightly.
MEDIA BAG: Use a suitable media bag when you want the 1-2cm pieces contained and easy to service.
AQUASCAPE USE: It can also be positioned as natural stone in planted or shrimp aquascapes. Account for natural variation and irregular edges.

FUNCTION & LIMITS

BIOLOGICAL-MEDIA ROLE: The porous rock provides textured surfaces for biological filter-media use when placed in a suitable filter route.
SECONDARY STONE ROUTE: The same natural stone can also add texture and structure in a supported aquascape route.
LIMIT: This is not quantified chemical ammonia-removal media and it does not establish a fixed pH, KH or GH effect.

CARE / REPLACE / REUSE

MAINTENANCE: Remove and rinse the rock during filter maintenance when needed.
REPLACEMENT: Use condition-led maintenance rather than a fixed replacement schedule.

Product-world scenes

Product-world scenes for Natural Volcanic Lava Rock

Illustrative BBA product-world scenes showing lava rock in removable media, aquarium and habitat contexts. These are visual context ideas, not filtration-result proof or water-parameter promises.

Habitat context

Removable media route

Lava rock shown contained in a mesh bag and filter basket, so the media stays easier to rinse, lift and maintain.

Detail context

Aquarium texture

Porous red-brown pieces can sit naturally around roots, moss and substrate when the layout suits that look.

Shelter route

Paludarium texture

A damp moss and drainage-style scene shows the texture route without implying water chemistry control.

Wide layout

Wide aquascape context

A broader planted scene shows how small pieces can support texture and depth in a natural display.

SAFE USE

Natural mineral dust and fines may be present.
Pieces vary naturally and may have irregular or sharp edges; position them carefully around delicate fish, bottom dwellers and burrowing livestock.
Do not treat the rock as a guaranteed ammonia, nitrite or nitrate remover.
