A large aquarium layout featuring Down (AGA 2025 #1132), 300 L (79.3 gal.), Aquatic Garden style, by the river by Udi Ben zvi. ADA La Plata Sand and ADA Aqua Gravel set the depth lines of the frame.
The hardscape with ADA La Plata Sand sets the rhythm; planting should support those lines without burying them. About 23 plant species are listed — fine for a multi-layer look, but keep a care log so slower species are not shaded out. ADA Cube Garden 120P, Ada amazonia ver 2, Ada power sand M, ADA Bacter 100, ADA TOURMALINE BC, ADA CLEAR SUPER substrate helps stabilize root-zone nutrition in the early weeks.
Chihiros Wrgb2 pro 120 lighting sits at a high technical level for this large aquarium. CO₂ (CO2 System with Inline CO2 Diffuser by Co2Art) — see our CO₂ systems if you want to clone a similar setup. Oase biomaster thermo 650 full with AQUARIO Neo Media Permium Soft + Oase biomaster thermo 850 full of BioHome media 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.
