A nano tank layout featuring Eden (AGA 2025 #1399), 25 L (6.6 gal.), Aquatic Garden style, by Richard Raven. The hardscape focus sits on Ohko Stone.
Read the stone and wood (Ohko Stone) as visual pathways before judging the plant mass. About 9 plant species are listed — fine for a multi-layer look, but keep a care log so slower species are not shaded out. ADA Amazonia substrate helps stabilize root-zone nutrition in the early weeks.
PF LUX M-600 lighting sits at a moderate-to-high technical level for this nano tank. CO₂ (DIY citric acid and baking soda CO2. 1-2 hours before light up and turn off with light.) — see our CO₂ systems if you want to clone a similar setup. Hang on Back Filter (RS-400/1600 L/H) 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.
