FORMULA FOR CALCULATING REQUIRED GRAVEL PER TANK
To work out how much sand or gravel you'll require to achieve a Two Inch (2") Gravel depth in your Fish Tank please use the following formula:

1) Multiply Tank LENGTH by Tank WIDTH (in inches) For example: 47" Inches x 19" Inches = 893
2) Divide the answer by 10. For example: 893 / 10 = 89.3
3) Convert to KG Kilogrammes by dividing answer by 2.2. For example: 89.3 / 2.2 = 40.5 KG REQUIRED

GENERAL GUIDELINES FOR 2" GRAVEL DEPTH

60cm / 2ft TANK = 25 kg
80cm / 2.6ft TANK = 30kg
100cm / 3.3ft TANK = 35 kg
120cm / 4ft TANK = 40 kg
These are approximates and of course you may want to have a deeper or thinner layer of gravel.
