Find a productProduct description
This lava substrate suits aquarists who want one material for both biological filtration and aquascaping. It is a good fit for sump and overflow filter setups, as well as biotope tanks where the bottom layer should look natural.
Why it matters
- High porosity: the open pore structure gives bacteria a large surface area to colonise, supporting biological filtration.
- Better water flow: the open structure keeps water moving through the substrate, which helps prevent anaerobic zones.
- Flexible use: the material works as a base layer under gravel, as filter media in sumps and overflow filters, or as a decorative element.
- Neutral to water chemistry: according to the manufacturer, it does not change water parameters and is safe for fish, shrimp and plants.
