OK, I left this up for a couple of weeks while I finished off the draft. So now it's finished, though I got no comments for change... so I assume it was either OK, or of no interest.
I can certainly see how someone might be hesitant to try this. But after everything I learned, it seemed a shame not to write it up for the community.
So, just in case someone out there might like to try this themselves, here's the first submission of how to build a 75g all glass tank.
As always, I'm interested in your feedback.
