Will the floor hold my 190g...

[quote=fishmanty]Joists= large boards the run across the ceiling and are only supported on the ends by other walls. If it runes parrallel to some, the weight won't be spread out enough, and could bring doing the single joist its on. /QUOTE]

In that case I believe it will run perpendicular to the joists which means the tank will have the load spread over three of them.
