5-Gallon High-Tech Iwagumi Aquascape (Intermediate)

Iwagumi aquascape example for a 5-gallon nano tank

A 5-gallon nano Iwagumi aquascape planned for a high-tech (pressurised CO₂) setup and a intermediate aquarist. It pairs 4 plant species with a 2-group stocking list, built around Seiryu Stone. Everything below is sized to the tank and matched to the intermediate skill level.

Hardscape & layout

Built around Seiryu Stone. Place the largest piece off-centre on the golden ratio, angled slightly back, with smaller supporting pieces stepping away from it.

Substrate

Aqua soil (e.g. ADA Amazonia / UNS Controsoil), built to about 2–3" deep. Active soil buffers soft, slightly acidic water and feeds roots. Slope higher at the back for depth.

Care schedule

DailyFeed lightly; a quick glance for anything unusual. Confirm CO₂ is on its timer.
Weekly25–50% water change, dose fertilizers, check the CO₂ drop checker, trim fast growers.
MonthlyRinse filter media in old tank water; test KH, GH, and pH; deep-trim and replant tops.
As neededTop off evaporation with dechlorinated water; spot-clean algae.
