I am salivating to get a 75g setup. The problem is that I live in an old building. Two issues, I am pretty sure that the joists are 16" apart but I am not sure of their orientation. Meaning are they side to side or run the length of my building. Does anyone have any tricks? I also need to find them. They are hardwood floors and I am not sure a stud finder can see that deep. I obviously can't ask my landlord, pets are allowed and I already have a 29g but this will weigh in excess of 1000 lbs. I cannot go to an exterior wall either. Thanks to all.
The lesser of two evils is still an evil.
