Determining floor/joist weight capacity

[dabandit]

Let me try to clarify this for everyone,the joists can bear the weight but it depends on how they are anchored,a saddle bracket alone cannot bear the prolonged constant weight. If you people want to risk it its your perogative,but reinforcing costs maybe 200$ what did your tank setup cost? or how much damage you think 100+gallons of water would cause?
