Step 1HardscapeAdd to build

Natural Seiryu Stone

Stone focal points for Iwagumi layouts

Why it fits: The sharp texture and gray tone make it easier to build a convincing Iwagumi composition.

Skip if: Skip it for very soft-water livestock because some Seiryu-style stones can raise hardness.

CaribSea Eco-Complete Substrate

Beginner-friendly inert planted substrate

Why it fits: Good fit for low-tech tanks because it is easier to manage than nutrient-rich aquasoil.

Keep lighting consistent

Why it fits: A timer is one of the cheapest ways to prevent algae from inconsistent or overly long photoperiods.

Aquascaping Tools Kit

Planting and trimming tools

Why it fits: Tweezers and curved scissors make planting stems and maintaining foreground plants much less frustrating.

Build Notes

Use the wide footprint to create depth instead of stacking too many rocks vertically.

A timer matters because long photoperiods make Iwagumi algae problems show quickly.

Choose easy foreground plants unless you are ready for CO2 and stronger fertilization.
