The following formula can be easily calculated:
L x T x H x 1,5
L = tank length
T = tank depth
H = desired level ground
1,5 = Factor Material Density natural sand
Beispiel:
tank length = 60 cm
tank depth = 40 cm
desired level ground = 4 cm
60 cm x 40 cm x 4 cm x 1,5 = 14,4 kg
You will need ca. 14,4 kg.
Thus, you could order the following package units:
1 x 10 kg + 1 x 5 kg
Or you can simply use our sand quantity calculator.
