I have a 43 gallon tank. I also have a good amount of live rock in my tank so I actually have less than 43 gallons. My question is how can I calculate my actual gallons based on how much rock I have in there, approximately? I am moving to an apartment that actually allows a tank this size on the 2nd floor but I want to be fairly certain it's within the 40 gallon size limit.
