Looks like they laid down some nice fat beads of silicone during the construction.
They use a lot of silicone in the process, they brought a box initially with I think 16 or more tubes. They've gone through over half of it I believe. Builders are tentatively coming back tonight or tomorrow to finish the rest of the tank!
To finish, cool! I bet it will be hard not to add water soon. But ya been planning the tank for so long maybe it won't be hard to wait a little longer. ;-)
Its actually very hard not to. I've been very good about staying away from the tank since the builders brought the glass in. I really want to go out and buy bulkheads and all the valves I need, but I'm trying to exercise my self control and wait until after the holidays.
Any updates yet?
Many, although I seem to be trapped by laziness lately....maybe later today.
