45P (10 gallon)

45P is a 45 × 27 × 30 cm (17.7 × 10.6 × 11.8 in) aquarium, about 36 L (10 gal) to the rim. Its footprint is 45 × 27 cm and the water stands about 24 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

  • 45P is 45 × 27 × 30 cm (17.7 × 10.6 × 11.8 in) — about 36 L (10 gal) to the rim, and roughly 27 L (7 gal) of actual water once a 6 cm substrate layer and the hardscape are in.
  • That layer takes about 7 L of substrate, which is what you order by.
  • 21 of the 160 animals in this library list a minimum tank at or under 36 L (10 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 24 cm (9.4 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 45 × 27 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?

45 × 27 × 30 cm (17.7 × 10.6 × 11.8 in).

How much water does it hold?

About 36 L (10 gal) to the rim, and roughly 27 L (7 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 7 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 24 cm sets which plants can grow without reaching the surface.
