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.

How to add fine sand to your aquarium fish tank successfully

Rinse the sand until water runs clear, then add to aquarium before filling. Make sure the sand is completely saturated and very wet beforehand.
Pat down the sand so it is flat and even across the base of your fish tank.

You can now fill your tank with water. You must break the fall of water so it does not disturb the sand too much.
This is important when the water level is still shallow.

Once your fish tank is full remove any small particles which may be floating. Switch on your filter and the tank will clear.
If you have powerheads / wavemakers in your aquarium, you should ensure these are not pointed directly at the sand.
