Gasha;4633294; said:if your worried listen to the creepyoldguy: just get insurance... i'm in the military so it's discounted from geico heavily but im sure it's cheap anyway.... btw i have a 140 gallons with 150lbs of sand and heavy drift on a 2nd floor apartment, it's on an outside wall going across the joists.... just make sure tank is level when you set it up and you'll be fine!! also i have talked to people who have kept 180 gallons on second floors for years with no sag.... and sag is what your worrying about, the tank will never, ever fall through the floor unless your house was built in a 3rd world country or by idiotic carpenters...
Lol seeing as how he said it was built 60 yrs ago, it really was "American made" When 2x4's really were 2x4's. I have a 150 and 180 both sitting on the same floor and did get a jack for the 180 and my floor didn't sag a bit. My house is probably over 100 yrs old with solid 2x8 joists on 24" centers.
