A large aquarium layout featuring Emerald Passage (AGA 2025 #1408), 300 L (79.3 gal.), Aquatic Garden style, by Ben Abraham Attokaran. Seiryu Stone and Lava stone set the depth lines of the frame.
The hardscape with Seiryu Stone sets the rhythm; planting should support those lines without burying them. About 17 plant species are listed — fine for a multi-layer look, but keep a care log so slower species are not shaded out. no Background substrate helps stabilize root-zone nutrition in the early weeks.
Chihiros Vivid II x 2 lighting sits at a high technical level for this large aquarium. CO₂ (40ppm Co2) — see our CO₂ systems if you want to clone a similar setup. High-tech balance means nutrients, light, and CO₂ must stay in step; one weak leg often triggers spot or hair algae.
