thinking about stackin 2 125's, make the stand out of 4x4's. Has anyone ever done this or heard of building a stand that holds 2 125 gallon tanks?
stacking two 125's

I haven't done it with 125's i did do it with my 20's. One thing to keep in mind is make sure there is enough space between them to properly do a water change on the lower one. Sounds like a no brainier but it sucks when you get everything set up and go to fill the lower tank and buckets don't fit.
No need for A LOT of bracing... wood is strong and 2x4's are overkill. Note the 1x3's holding up these big tanks.
I would use 2x4's they're cheaper.

I did this several times in the past. The 2x4s are a better option than 4x4s. 4x4s tend to twist and are not ideal pieces of wood to work with. They have their purpose, but this isn't it. Go with 2x4s and you'll be more than fine.
I used cinder blocks for the uprights, and 2x6's for the tops. I am stacking 2 90 gallon tanks, one sits on the floor and the other sits on 3 stacked cinder blocks glued together with a liquid nails type of product. I am actuall going to go one higher and stack a 50 long on top of this.
2x6's were needed due to having the filter for the bottom tank on the side(the 2nd tank is offset).

Cinder-blocks are just overkill [1250 PSI - 5000 PSI test strength]

So the worst piece of 2x4 under compression can hold 635PSI
Also if you think about the construction, what you use as posts will be outside the dimensions of the tank making the shear strength of nails or screws the most important part. if your design allows for bolts they are stronger[bolts are rated in KSI which makes them silly strong for this application]
