How much gravel do i need in my tank?

As a very rough guide for every 1ft length of Aquarium approx 10Kg of sand or gravel is required. This will give approx depth of 1.5" or 40mm

The calculation is as follows

Length x Width divided by 10. This then give the weight required in Lbs. To convert this to KG just divide the answer by 2.2

For example on a 4ft x 1.5ft long tank

48(inches) x 18(inches) = 864 divided by 10 = 86.4(lbs) divide again by 2.2 = 39.27KG

  • Nordic natural gravel approx 4 to 6mm in diameter
  • Ideal for freshwater tropical or coldwater aquariums
  • Great substrate for aquarium tank plants
