Hey guys, I was wondering how much do fish tanks weigh on average? Does anyone have weight per gallon ratios? Obviously one would have to factor in sub strait, rocks, stands and a few other factors. Reason I ask is that since I someday would love to have a huge tank around the 160g - 249 range. It would stand to reason that putting that kind of weight on a wood surface can do damage over time. At least it would seem so.
