For example, if your tank is 20 inches long and 10 inches wide, and you want a 1-inch gravel layer:

20 x 10 = 200 square inches. For a depth of 1 inch, you’d need around 10 pounds of gravel.

Factors Affecting Gravel Quantity

Keep these in mind when you shop for gravel:

  • Tank shape: A tall tank may need less gravel than a long tank.
  • Gravel size: Larger pieces mean fewer will fit, changing the weight needed.
  • Plants: Live plants may require more gravel to root properly.
  • Decoration: Plan more gravel to secure decorations.
  • Filtration: Under-gravel filters influence how much and what type of gravel to lay down.

A personalized approach ensures your tank looks great and your fish flourish.
