Nano Reef Tank Setup Guide — Keeping Corals in 30-45cm Tanks

For those with limited space, nano reef tanks (30-45cm) offer a way to enjoy coral keeping. With proper equipment and management, beautiful reef tanks are possible even in small volumes.

Suitable Tank Sizes

• 30cm cube (~27L): Minimum size, demanding management
• 40cm cube (~64L): Best balance, recommended
• 45cm (~40-50L): Good layout flexibility

Nano Reef Equipment

Compact high-PAR LED, hang-on skimmer, 50-100W heater, and a small wavemaker.

Best Corals for Nano Reefs

Zoanthids, mushroom corals, small Lobophyllia, star polyps, and Clavularia. Stick to soft corals — SPS are too demanding for small water volumes.

Nano Reef Water Management

Weekly 15-20% water changes, careful evaporation monitoring (auto top-off recommended), and cooling fans for summer.
