A mid-size aquarium layout featuring The hidden hollow, 121 L (32.0 gal.), Aquatic Garden style, by Claudio Sartor. Dragon wood and Dragon stones set the depth lines of the frame.
Hardscape (Dragon wood, Dragon stones) forms the skeleton — negative space between wood and stone guides the eye from foreground to depth. About 27 plant species are listed — fine for a multi-layer look, but keep a care log so slower species are not shaded out. ADA Power Sand Advance, ADA Amazonia, Ada Amazonia powder, Bacter 100, Tourmaline BC, Clear super, ADA Colorado Sand substrate helps stabilize root-zone nutrition in the early weeks.
Chihiros Vivid 2 10th Anniversary lighting sits at a high technical level for this mid-size aquarium. CO₂ (2 bubbles/sec) — see our CO₂ systems if you want to clone a similar setup. Oase Biomaster 600 with ADA Na Carbon, ADA Bio-Rio G, Seachem Matrix, Seachem Purigen filtration needs enough turnovers without blasting the hardscape; browse matching filters. High-tech balance means nutrients, light, and CO₂ must stay in step; one weak leg often triggers spot or hair algae.
