Dennerle Nano Cube 30L

Dennerle Nano Cube 30L is a 30 × 30 × 35 cm (11.8 × 11.8 × 13.8 in) aquarium, rated at 30 L (8 gal). Its footprint is 30 × 30 cm and the water stands about 29 cm deep once a 6 cm substrate layer is in — the two numbers that decide what you can plant in it and what you can stock it with.

Before it goes in

  • Dennerle Nano Cube 30L is 30 × 30 × 35 cm (11.8 × 11.8 × 13.8 in) — rated at 30 L (8 gal), and roughly 24 L (6 gal) of actual water once a 6 cm substrate layer and the hardscape are in.
  • That layer takes about 5 L of substrate, which is what you order by.
  • 21 of the 160 animals in this library list a minimum tank at or under 30 L (8 gal). The biggest of them that still fit are Ember Tetra and Chili Rasbora. African Dwarf Frog and African Clawed Frog need more than this.
  • The water sits about 29 cm (11.4 in) deep over the substrate. Plants that get taller than that — Hygrophila corymbosa 'Siamensis' and Water Sprite — reach the surface and start growing along it, which is a look you either want or trim.
  • Its footprint is 30 × 30 cm, and that is the area a carpet has to cover — the number that decides how many pots you buy, not the volume.

What are its dimensions?

30 × 30 × 35 cm (11.8 × 11.8 × 13.8 in).

How much water does it hold?

It is sold as 30 L (8 gal), and roughly 24 L (6 gal) of actual water once the substrate is in. Stocking works off the second number; minimum-tank-size advice works off the first.

How much substrate does it take?

About 5 L for a 6 cm layer.

What fits in it?

21 of the 160 animals in this library list a minimum tank at or under its volume, and the water depth of about 29 cm sets which plants can grow without reaching the surface.
