I mean this in no sarcastic manner at all, but I've been wondering the same thing since I've been in the market for a 265 and I finally just pulled the trigger on it and bought one today.
This is what I've always wondered. I have a 120gallon right now, and the stand has lasted 5 years and it weighs literally nothing, and theres not much too it at all. It is on the second floor (FROG room of my house) I never really understood why people worry so much about tanks falling through floors and sagging the floors, but we put so much trust into these puny stands, but do not trust the floors in our house. What am I missing?
Disclaimer- I know nothing about construction, and this might be where I dont get it, but Ive never understood how a tank stand can support a weight but a whole floor in a home cant.
