WIO Black Venom Boulders are stunning vibrant pitch-black colour boulders. This rock fascinates for its smooth black-glazed surface, design possibilities are endless due to its excellent colour contrast and maze-like texture. Black Venom Stone is a high-impact rock that magnifies the green of plants and moss. It is an ideal stone to create Iwagumi and as a complementing stone for ryoboku layouts.
Mix and match with Black Venom Gravel and Heaven River Sand to achieve a high impact composition.
Tips:
Most WIO boulders come completely clean. Even though, we recommend to rinse them with water before use to remove any remaining dust and to avoid buoyancy of particles on the water fill up.
We highly recommend you to mix different sizes to create depth in your aquarium. By doing so, it will also look more natural.
You can easily test if a stone 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 stone contains some calcium.
Stones 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 with osmotic or soft water. You can also use a water softener.
