A large aquarium layout featuring Gravitas, 300L, by Walid Khalid. The hardscape focus sits on Amazonia 2 aquasoil.
Hardscape (Amazonia 2 aquasoil) forms the skeleton — negative space between wood and stone guides the eye from foreground to depth. The plant list (Hemianthus micranthemoides) favors foreground carpeting; packing the foreground too dense can make the tank feel heavy.
Chihiros wrgb2 pro '60' × 4 lighting sits at a moderate-to-high technical level for this large aquarium. Canister5 ×2 SunSun+Dophin filtration needs enough turnovers without blasting the hardscape; browse matching filters.
Use the specs table as a shopping checklist for equivalent gear — then explore 220–320L.
