Rainbow gravel is a mixture of various coloured gravels to give a multicolour substrate to your fish tank. With a grain size of 3 to 8 mm it a standard size for an aquarium gravel substrate.

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
