Pressure foam under large aquarium advice
Setting up a 72" long 125 gal on a support I already know is irregular so I need to compensate all that I can. I've run up on this Youtube video showing the use of what is called pressure foam or possibly polystrom to help compensate for my kind of tank support issue. I've searched a couple online aquarium supply stores but I haven't been able to turn up any such product.

Here's the video...

Did a search on polystrom and it seems like it's out of Australia, and I'm guessing there's a US equivalent.

Does anyone know where I should look for this kind of foam?

It's expanded polystyrene, or styrofoam here in the US.
Go to any of the big box builder supply stores and get a sheet of 1/2 inch insulation styrofoam and cut what you want out of that, it comes in 8 foot by 4 foot sheets.
You can cut it with a standard saw, and sand the edges smooth, makes a real mess though.
Sometimes the store will cut it for you, if you ask nicely
I think pink is the most common color, but the blue is firmer and might be more suited to your needs.

Correct. I bought a roll of turquoise-coloured and folded it over for two layers. I think I got it at Home Depot, it was back in 1996.
