Hi all, I'm new to these forums 
Just bought an aquael bowl and starting to set it up
So, my question is, the water volume you refer to when calculating stock etc, is it what it says on the box, or is it the actual amount of water you put in?
This bowl says 25l, but I only got 23 in and I'm planning on adding some sand to the bottom, which will reduce it further.
Thanks for any help
