Anyone an engineer? Tank placement question (townhouse)

[originalozzyo]

I lived in a wood frame apartment for 3 years on the fourth (top) floor and had 155 gallon tank with 30 gallon sump in my living room. This was concrete 1" skim coat over plywood floor and standard spacing 2x10 joists, maybe 8-12" spacing using a stud finder. BCAA insurance said no problem even after I asked them multiple times about a tank this size. I think you will be fine, I was nervous for months until I just accepted it and even forgot about it
