FormulaSubstrate bulk volume = length*width*(front+back)/2/1000; Substrate bulk mass = length*width*(front+back)/2/1000*density; Bed slope angle = Math.atan((back-front)/width)*180/Math.PI

Made for real tasks

How to use this tool

  1. Enter inside tank length, inside tank width, front substrate depth, back substrate depth, and measured bulk substrate density in the displayed units.
  2. Calculate and use each labeled result for aquarium sloped substrate quantity. Compare the result with a measured sample before committing materials.

Try this example

{
  "length": 90,
  "width": 40,
  "front": 3,
  "back": 8,
  "density": 1.4
}

Accuracy and scope

Substrate purchase quantity, not displaced-water volume: pores can hold water. No recommendations about animal suitability or substrate depth.
