Calculate the weight (in lbs.) for a desired substrate depth in your aquarium with this simple utility. (i.e. How much sand/substrate am I going to need for my tank.)

You should add enough sand to get a 3-6" sand bed.  The deeper the bed, the better... however if you have a shallow tank, you may not wish to have too deep of a sandbed as it will limit the amount of room in your tank.  For tanks under 30 gallons I suggest a 3-4" sandbed.  For tanks over 30 gallons I suggest at least a 5" sandbed.
