A large aquarium layout featuring Passage (AGA 2025 #1031), 300 L (79.3 gal.), Aquatic Garden style, by MARCOS CARRA'H JÚNIOR. The composition is built around Wood with Ada rock Ryuoh.
Hardscape (Wood, Ada rock Ryuoh) forms the skeleton — negative space between wood and stone guides the eye from foreground to depth. About 2 plant species are listed — fine for a multi-layer look, but keep a care log so slower species are not shaded out. Ada aqua gravel; Aqua soil Amazonia version 2 Ada; Substrate Additives bacter 100; Substrate Additives Clear super; Substrate Additives Tourmaline BC; Ada La plata sand. substrate helps stabilize root-zone nutrition in the early weeks.
use of chihiros RGB VIVID lighting during photoperiod of 8 hours per day. lighting sits at a high technical level for this large aquarium. CO₂ (45 ppm CO2 durring 8 hours per photoperiod. Use of 4 kg co2 system during photoperiod.) — see our CO₂ systems if you want to clone a similar setup. use Sun Sun of 2000 l/h canister filtration with UV and installation in a chiller with water temperature at 25 degrees Celsius. 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.
