I'm thinking about getting rid of my 29 gal nano cube in my bedroom which is on the second floor of my house. Im curious to how much weight I could put upstairs, im about to purchase a 60 gallon rimless cube with a 20 gallon sump. I was originally going to put it in the kitchen but I think it would look amazing in my bedroom. Would anyone say that I could go bigger, the house was built in 2007 so its not built as strong as the older houses. I would like to hear a few opinions.

Lots of variables come in to play and without knowing them it is impossible to give a definitive answer. (size,type,span, location,direction, supports underneath etc.) I totally disagree with it not being as strong as the older houses. Many of the newer engineered floor systems are much stronger and predictable vs. the older dimensional lumber houses. All that said I believe that your floor system is typical it will have no problems supporting a 60 cube. Any bigger and I would educate myself before hand as to the aforementioned variables .

Thanks for the info, I think I will stick with the 60 cube
 
I had a 90 with 30 sump on main floor over my basement. About to do a 250 with 75 sump in the same spot but bracing the floor just in case.
 
I can't imagine it would be a problem. Structural engineers will use a Factor of Safety when designing. Typically they design things to be much stronger than they need to be.

I have a 72g with a sump on the second floor of my house, no problems.

More than likely it would handle a much larger tank. Without examining it closer or more info on what is there it would be ridiculous for me or anyone else to tell you it would for sure be Ok. Most of the floor systems in the last 30 years would hold a 300+ gallon tank with no problem notice I said hold. The problem is when the weight starts to flex the floor system and in return the tank moves as well putting undue stress on the silicone seams. I just helped an individual clean up a 210 7 year old Oceanic tank which was placed on a floor system that had too much give in it. The seams finally gave way.Rough estimate is around $25,000 in damages excluding the tank and animals.
 
Only thing i make sure of is that the tank runs perpendicular to the floor beams and check for flex if possible. and its always good to put a level on the tank, make sure it has a good flat spot. on the main floor over my basement ive got a 135, 50, 55, and a 39g.
 
I live in a house built in the 1950s. It is elevated about 3ft off the ground on cinder blocks. Its held my 120 reef no problem for over a year now. I did put it in a corner and made sure the floor boards ran the opposite direction of the stand.
 
I have a 65 gallon tank on the 2nd floor and I live at the school apartment lol
