well thanks guys for all your input....I was living with three mechanical engineers (I'm an electrical engineer...not my expertise) when I set it up......they moved out yesterday. We did all the Calculations for the tank and I think we may be only 30 lbs or so Off....... Empty Tank Wieght = 206lbs, Water = 8.34 * 125 = 1042.5, Stand= 120lbs, Sand Wood Wet-dry filter and Lights = 150 lbs. So I'm looking at roughly 1518.5 lbs in an area of 18inches X 6 feet...........I walk lighty around it
Not a bad idea, but normally a floor wil easily hold your tank.I would definately check with a structural engineer.
My last apartment was built in 1995. I lived on the first floor with a basement underneath me. Just the weight of my 220 glass aquarium (no water), stand, canopy, and gravel separated the floor of my room from the wall 3/4 inches. This was also a load bearing wall, perpendicular to 8 floor joists and nothing else in the room. Your tank filled weighs about twice what mine did unfilled.
You might also consider getting insurance for your tank.
Now yesterday I did some research on my building and found out that my floor can take a live load of 40 lbs/foot I am running 166lbs/foot with the fish tank!!
