Just got done with reinforcing the floor. The cross beam is a 4x6x8 and is supported by two jack post from homedepot. Jack post base is resting on a 12x12 pyramid block, the post on the left is on 2 blocks b/c it wasnt high enough. The ground is kind of like clay, but does not sag when I jump on the blocks. The 180 gallon tank will go right behind a refrigerator on the first floor and will be in the middle of the 2 jack posts. So my question is, will this setup support my tank setup? anything i should worry or keep in mind? thanks.
