I would like for it to be acrylic as it is much stronger and about half the
weight of glass. I was thinking about building a tank about 8 feet long and
about 4 feet deep (front to back) by about 5 feet high (floor to ceiling).
This may be well beyond 300Gs, I don't know (that's why I was asking about
the thickness calcs and stuff). Basically the tank is gonna be the main
reason for a room in my house. It is being used for nothing else now so why
not up the house's value ... Thanks for the info on the sealants and
blades. Any links to thickness calcs for acrylic would be great and also
water weight calcs...I'm not having much luck myself.

I make that to be about 1735 gallons

I generally guess about 10 pounds per gallon to account for water,
tank, substrate, whatever else is in there.
