A large aquarium layout featuring Harmony City, 300 L (79.3 gal.), Aquatic Garden style, by Chow Hiu Wai. Pine Stone set the depth lines of the frame.
The hardscape with Pine Stone sets the rhythm; planting should support those lines without burying them. 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 La-Plata sand, Ada aqua soil substrate helps stabilize root-zone nutrition in the early weeks.
Netlea lighting sits at a approachable technical level for this large aquarium. Low-tech tip: favor slow growers and avoid dense planting if filtration is modest.
