"Plexiglas G acrylic sheet"

[brackishdude]

good stuff for sumps, aquariums, etc?

Yes, the G is the better stuff.

Good in that it is cell-cast material. Overall, probably third in line behind Spartech G and Acrylite GP. Those two are domestic, Plexiglas G is probably the best of the import brands. That said, more than sufficient for most projects.
