Moving houses, need opinions on floor bracing

[Sasq40]

So I'm moving in a week and trying to get prepared for the fish tank. Its a 2 story house with a 4ft crawl space underneath. The fish tank will be going on an outside wall parallel with the joists. Its a 160 bow front(6x24x24(18 at the edges) The floor is 16 joist so the tank will be sitting on 2 joists. There are 2 support beams 63" from the left side of the tank and 29" from the right side of the tank.

My thoughts are to add 2 floor jacks under the front to corners were the tank would be, with a 24x24 cement block as well as a piece of lumber, probably 4x4 or rough cut 3x12(i have alot from work) to help spread the load over the cement. The crawl space is dirt floor but the water level is quite high right now so doing a footing may be difficult, but not impossible(would have to dig to find out)

Also I'm thinking of moving my sump into the garage, which is probably 8' ft away from the tank, on the rear wall. So i would be routing my plumbing behind the tank, then into the garage(which is sunken about 1' below the living room) Ive been looking at large plastic tanks to use as my sump(id imagine probably best bet would be to get external pump and skimmer) I suppose my main concern is the draining of the tank(right now im corner overflows with 1 & 3/4 bulkheads). Basically as long as my sump is lower then the highest drain point then will it still drain going that long of a run?

I dont plan on having the plumbing done before the move, but i know i need to get the bracing done before the tank goes into place. Any and all help appropriated!!!
