Natural volcanic lava substrate for planted and freshwater aquariums. Its porous structure maximizes beneficial bacteria colonization for biological filtration, prevents soil compaction to promote deep root growth, and remains 100% inert to keep pH and water parameters completely stable.
| Slope Stability: Interlocking grains hold steep aquascape slopes without shifting.
| Nutrient Binders: Traps nutrients to feed roots and starves water-column algae.

3–8 mm irregular granules
100% Natural
Custom-packed to your exact order (from 1 kg to 20 kg+)
Sourced directly from 100% natural volcanic deposits, Aquatees natural volanic substrates are completely unrefined with zero dyes, coatings, or synthetic additives. Before adding it to your tank, give it a quick rinse in a bucket to wash away natural transit dust. Safe for all fish, shrimp, and live plants, this versatile rock works as a rich standalone substrate, a high-flow base layer under soils, or active biological filter media.

Multiply your tank's length × width × target depth (in cm), then divide by 1000 to find the total liters needed. Because 1 kg of our porous lava rock yields roughly 1 to 1.2 liters of volume, purchase approximately 1 kg per liter of calculated space (add 10–20% extra if sloping toward the back).
Yes. Rinse thoroughly in a bucket or strainer under tap water until the runoff is clear to remove natural rock dust from transit.
No. It is 100% inert volcanic rock, meaning it will not alter pH, KH, GH, or TDS parameters in freshwater or marine setups.
Yes. It is fully non-toxic and natural. For delicate burrowing species, pair it with a fine sand cap or active soil top layer.
Yes. It is 100% chemically inert, making it completely safe for both freshwater and marine aquariums without leaching unwanted minerals or metals.
