A nano tank layout featuring Where the rainbow has fallen, 30 L (7.9 gal.), Riparium style, by Johan Park. The composition is built around Oak drift wood only.
The hardscape with Oak drift wood only sets the rhythm; planting should support those lines without burying them. About 15 plant species are listed — fine for a multi-layer look, but keep a care log so slower species are not shaded out. Nature farm – Nature sand 'Bright' substrate helps stabilize root-zone nutrition in the early weeks.
Aquas Metal light spot lighting sits at a moderate-to-high technical level for this nano tank. CO₂ (not use CO2) — see our CO₂ systems if you want to clone a similar setup. Bottom sump filtration needs enough turnovers without blasting the hardscape; browse matching filters. On nano tanks, ramp light intensity over the first 2–3 weeks to limit hair algae.
