Simply rinse before use. Some substrates (particularly sands) naturally contain more fines than others and may require additional rinsing and more time to settle in an aquarium.Spread substrate evenly and fill with water slowly. We suggest placing a plastic bag over the area where you are filling with water to avoid stirring up the substrate.Once the tank is filled, start your filter. Any cloudy appearance should clear within a few hours(sands will take longer).
