, I ordered my glass from a local glass shop.

Glass window- $600

If you calculate based solely on the gallons of water in the tank itself, it comes out to $1.94 per gallon. If you calculate with the extra water in the sump which technically since it was part of the build so you should it comes out to $1.74 per gallon.
