he Elderly Boulder from the WIOdecor Stones series by manufacturer WIO are river nano stones that give a natural impression of a riverbed of rolling stones. Elderly Nano Boulders are richly textured, striped and have a cold colour palette that makes the underwater landscape look attractive and natural. The positioning of the different sizes of Elderly Boulders in combination with Elderly Gravel invites to get creative and create a handsome depth effect in the aquarium. By using Heaven Sand preserved, an extremely attractive contrast can be created.


  • Natural, cold colours
  • Round edges give the impression of rolling river stones
  • May slightly increase the pH value and the KH
  • Can slightly harden the water
  • Available in 2 kg containers


These stone sets are unhalndled natural products. It is recommended to clean and rinse the stone decoration under running water before using it in the aquarium. This removes the finest stagnant particles, which can otherwise cause cloudiness when a new aquarium is set up. Slight residues of moss or lichen cannot be completely ruled out.
