Aquarium Volume

Knowing the correct volume is important when it comes to stocking. It is absolutely critical when it comes to using treatments.

Theoretical volume:
This is the absolute volume when an otherwise empty tank is filled to the very top edge with water.

Realistic volume:
Allows for decor displacement and that the tank won't be filled to the very top edge. As such this is a far more accurate measurement to use.
