Usage

• Spread the pebbles evenly along the bottom of your empty tank or terrarium; pour gently from a low height to avoid scratching the aquarium glass
• Use on its own for a natural base, or combine with other WIO sands and gravels for a custom substrate look
• Arrange rocks, driftwood, and plants to create a harmonious and captivating environment
• When filling the tank, pour water carefully avoiding direct flow onto the gravel — Pro Tip: pour over a plate or décor to minimize disturbance
• Use a net to skim any floating particles, then turn on the filter and watch the remaining cloudiness disappear within a few hours, leaving a clear, natural finish
• For maintenance, regularly vacuum clean the pebbles with every water change to remove any accumulated debris or algae
