To work out how much weight of gravel / sand for a 2 inch deep bed you need for an aquarium (or any area of space) use the following formula; 1) Times your tank length by your tank width (in inches)e.g. average 120cm tank - 47 inches x 19 inches = 8932) Take this figure and divide by 10e.g. 893 / 10 = 89.33) This is your weight required in pounds - for Kg divide this figure by 2.2e.g. 89.3 / 2.2 = 40.5kgSo for a normal 120cm length tank for two inches of gravel you will need roughly 40kg.If you only want 1 inch of gravel please multiply this figure by 0.5 (20kg) and for 3 inches please multiply this figure by 1.5 (60kg).
