Midnight River Sand from the WIOdecor-Sands series by the manufacturer WIO is a matt black decorative sand with variable grain size between 0,1 - 2 mm.
Due to the very dark, matt black colouring, this sand fits perfectly with Soil. The design of a natural riverbed can also be excellently created with this sand. By combining it with light-coloured plants or other light-coloured sand types, complex contrasts can be achieved.


Midnight River Sand - left dry, right wet

Sand is usually a passive substrate that does not provide nutrients for the aquarium plants. Therefore, when setting up with sand as the sole substrate, the use of substrate fertiliser can be necessary. Fertiliser balls or tablets can be used to enrich specific parts of the aquarium with nutrients, so that especially plants with strong roots, such as cryptocorynes, can benefit from this.


  • Especially dark colouring
  • Natural quartz sand
  • Grain size from 0,1 to max. 5 mm in the mix
  • Does not harden the water
  • Available in containers of 2 kg


All WIOdecor sand types are pre-washed. Nevertheless, the manufacturer recommends briefly rinsing the sand with cold water before use to wash off any abrasion caused by transport. This also helps to prevent grains of sand from floating up when filling the aquarium.
