hey guys I am very worried about putting my tank on the second floor. I have a 75 heavy stocked tank there now. the 125 will be a little bit more. anyway I know that the tank will sit on a support beam and the floor joist run perpindicluar(sory spell error) to the tank. I also know that the tank will spread weight over 7 floor joist. do you think this will hold the tank?? my house is 27 years old. any input will help. thanks
