you might not initially go through the floor, but i dont think you all would be planning on standing in the same spot for a couple of years... one of the biggest problems that people forget about is the time factor.Ok, a 125g wold weight about 1,000 pounds water only.
Factor in stand, tank, filter, substrate, ect, you end up with about 1,500.
If about 8 people of average weight (150-200 pounds) stood in a tight circle, would they go through the floor?
I have been worried about this too with my 55g, but every time I start freaking out, I just think of it like that. If me and 3 of my friends stood together, would we go through the floor? Umm, no.![]()
take a look at this page, it'll give you a better idea of the do's and don'ts of aquariums and weight tolerances.
