Weight of a 4 footer tank.

Need advice, I just bought a 2nd hand 4x2x2 tank, but this tanks glass is quite thick, its 1/2 inch. I noticed its weight is really really heavy.
was planning on getting a 4x2x2 but with 3/8 glass only , but got this instead


now my problem is i currently have a 4x1.5x1.5 ft tank.

i'm planning to replace with a 4x2x2.
whats would be the weight difference of a 4x2x2 tank with 2/8 glass and 1/2 inch glass?
also what would be the weight of a 4x2x2 tank with 1/2 inch glass filled with
water compared to a 4x1.5x1.5 ft filled with water? i'm a little hesitant since our floor is wooden. would replacing the tank with a 3/8 inch glass be better?

here's a picture of where the tank will be placed. replacing the 4 x 1.5 x 1.5 ft tank. does it look like the floor can take the weight?

There's really no way to tell how strong your floor is by looking at it from above. Can you see the floor structure from below, or get access to the building plans? Is the wall that the tank is against a load-bearing wall?

The difference in weight of the glass is negligible compared to the filled weight. A filled tank with gravel and all weighs about 10 lbs. (4.5 kg) per gallon of volume.

4' X 1.5' X 1.5' = 67 gallons = 670 lbs. (300 kg)
4' X 2' X 2' = 120 gallons = 1200 lbs. (545 kg)

agreed. never skimp on glass thickness. otherwise you can have a flood..

thanks What do you mean by a load bearing wall?
I'm not 100% sure, but below the floor there are wooden beams perpendicular to the wooden floor. I think about 1 foot apart, the beams if i remember correctly are 2 inch x 4 inch each. Any way to spread the pressure on the floor?
