Converted Aquarium

Repurposed tank with a lid — huge volume for bioactive landscapes.

Old aquariums make excellent humid cabinets when fitted with a proper lid and light. Volume stabilises climate and supports deeper substrate.

When to choose

Choose this when you can dedicate floor or stand space and want a serious living landscape.

Ventilation notes

Cross-vents near the top reduce stale corners. Open the lid weekly for inspection.
