Bring the warm, earthy tones of the Congo River delta to your aquarium with the Mere River Kit. This all-in-one kit creates a rich and engaging scape perfect for mimicking the habitats of deltas, lakes, and lagoons — a landscape defined by warm ochre tones, varied stone sizes, and the inviting glow of sun-drenched riverbeds.

At the heart of the Mere kit is the Bumblebee Stone — a natural yellowish ochre sedimentary stone with smooth textures and warm palette tones that perfectly evoke the rounded, water-worn boulders of tropical river deltas. The kit includes a carefully selected range of Bumblebee Stone pieces from XL down to small, alongside a 2 kg bag of Bumblebee Nano Boulders for foreground detailing and natural depth. The warm tones are grounded by the Mere Biotope Beds — a curated 2 kg blend of natural biotope substrate material — and supported by Artist Mustard, a 5 kg nutrient-rich plant substrate that delivers the foundation for healthy plant growth with warm golden undertones.

The result is a warm, layered riverbed that feels genuinely discovered — ideal for West African biotopes, delta-inspired scapes, or any layout seeking an inviting, sun-kissed ambiance.
