It is an ideal stone to create Iwagumi and as a complementing stone for ryoboku layouts.

Mix and match with Black Venom Nano Boulders and Wio Heaven Sand to achieve a high impact composition.

*An ideal stone for Iwagumi layouts.

Please follow our recommendations to enjoy our boulders: 

  • Most of our boulders come completely clean. Even though, we recommend rinsing boulders with water before use to remove any remaining dust.

  • You can easily test if a boulder is inert or if it will change slightly the pH and hardness. Simply place few drops of vinegar on the rock. If the vinegar (a base substance) fizzes or foams, it indicates that the gravel contains some calcium.

  • Boulders that contain calcium may alter the pH and kH. This can be especially pronounced if you have acidic water or CO2 addition. You can easily control it by regular water changes.
