A clean, ultra-fine black sand accented with subtle white specks that give your tank a natural, high-contrast look. Engineered to settle quickly and resist clouding, it stays completely inert so your pH and water parameters don't shift.
| Fast-Settling Formula: Specialized grain structure reduces dust and clears water quickly.
| 100% Water-Neutral: Won't alter your pH, KH, or overall water chemistry.

0.5mm – 1.0mm Fine Granules
Synthetic, Silicate-Based
Custom-packed to your exact order (from 1 kg to 20 kg+)
Engineered from high-purity synthetic silicate, this sand provides a smooth fine grain bed with zero pH or buffering effects on water chemistry. A thorough pre-rinse in a bucket removes transit dust, while the dense, striated granules allow remaining particles to settle quickly. Safe for fish, shrimp, and live plants, the soft-edged sand protects delicate barbels, prevents debris from sinking deep into the bed, and provides a stable, inert anchor for root systems.

Multiply your tank’s length × width × target sand depth (in cm), then divide by 714. This accounts for the sands density of roughly 0.714L per kilo to give you the precise weight needed in kilograms.
(Example: A 60 cm × 30 cm tank needing a 4 cm deep sand bed requires 60 x 30 x 4 / 714 = 10kg of Fine Black Sand.)
Yes. A thorough rinse in a bucket removes micro-dust generated during shipping and ensures your water clears rapidly after filling.
No. It is 100% chemically inert and will not alter pH, KH, or GH.
Because the dense synthetic grains settle tightly, detritus rests on top of the bed rather than sinking deep. Hover your gravel siphon slightly above the sand bed to vacuum waste without pulling up grains.
Yes. It is chemically stable and will not react with salt water. However, it provides zero pH or alkalinity buffering, so proper marine parameters must be maintained via salt mixes and buffers.
Yes. It provides a dense, stable anchor for root systems, though as an inert substrate, you will need to add root tabs or liquid fertilizers for heavy root-feeders.
