How many litres is my tank?

It is important to know just how many litres your tank is so that you can be accurate when adding or dosing items like medications and de-chlorinators.

To work out just how big your tank is simply multiply in centimetres the width by the height by the length then divide by 1000.

Also keep in mind that you will be best to measure to the waterline rather than the top of the tank when working out how much water is in the tank.

For example a 4 foot tank may measure 120cm in length by 45cm wide and 45cm high.
  • 120 X 45 X 45 = 243000
  • Then divide by 1000 which would make this tank 243 litres
