Please HELP!!! Can 2x4 studs support this weight? Hi All, New to the Forum and have a question. I want to put an aquarium (220Gallon) on a loft in the third floor Condo I will be purchasing. My guess of the total weight of the tank is close to 3000lbs filled. The Tank is 72"Length x 24" Deep x 30" tall. I do not own the First floor but i do know they have a concrete foundation. The loft is 22'x15' My Plan: Place the aquarium against an outside wall (Load Bearing) therefore i will catch at least 4 floor joist (2x6) that has a span of 12ft. Each end on a load bearing wall. The outside walls are very likely using 2x4x8 on both the first and second floor studs. Should I?: * Add additonal Floor joist and if so how many? I figured double up. * Add 4x4 inside the wall below since there is a window under there also. Additional Info: The tank stand will have 6 - 8 legs resting on a 2x4 or 4x4 to spread the weight out evenly. In addition I was going to set the tank 6"-10" away from the wall to shift some of the weight to the other load bearing wall. BTW - Do I need to support the walls in the first floor also. I figured the weight will be distributed over a longer span by the time it gets down there. I hope not since I do not own that floor. Is my calculation correct? 3000/12(sq feet) = 250lbs/sqft. Open to any suggestion. Thank you for all you assistance.
