This lava media suits keepers of decorative and planted freshwater aquariums who want a porous base layer beneath their top substrate. The 4–8 mm grain size and 2 kg pack make it a practical option for setting up or extending a filtration substrate.
Why it matters
- Porous structure: The natural volcanic lava offers a large surface area for nitrifying bacteria to colonise, which supports the nitrogen cycle.
- Improved water flow in the substrate: The lava structure allows water to circulate through the bed, which the supplier states helps prevent debris buildup and anaerobic zones.
- Natural rust-red colour: The lava forms a contrasting layer below gravel or sand, adding visual depth to the tank.
- Pre-rinsed, but rinse again: The product is pre-washed; the supplier recommends an additional rinse before use.
