Ocean Max gravel 1kg 3-5mm.

• Rinse with lukewarm water before use.
• Cover the bottom with a layer 3 to 10 centimeters thick.
• Let the gravel move towards the back, so that dirt always collects at the front of the aquarium and is easy to remove.
• If you have live plants in the aquarium, it is recommended to first apply a layer of food or food pellets underneath the gravel.
