For planted aquariums, a size range of 2 to 5 mm is ideal for most plants. In general, it is suggested to avoid very light colored substrates, as they can make fish appear less colorful. If epoxy coated gravel is being used, make sure to avoid rinsing with hot water and excessively agitating when cleaning, to preserve the epoxy coating.

Use the gravel to aquascape and create a depth perspective. Slope from back to front and employ some terracing to provide deeper areas. This also benefiting plants which have heavier root networks, such as the larger Echinodorus species.
