Roommate went to a party, so I was able to get some work on the floor done. I still have to fill in all the short pieces, so before you ask, yes, there's going to be 3 layers of 2x6s throughout the entire floor support frame. What's great about needing short pieces is that I'm able to make use of all the short pieces of 2x6 that I have from cutting all the other boards. Very little waste from this project.
One thing I didn't do with the seal that I wish I had is apply it to the acrylic instead of the wood frame. In hindsight, it would have gone much easier that way. I guess my thinking got thrown off by going with someone's good suggestion to dry fit the acrylic, tilt it back after, then apply the dow 795. Ken wasn't there as my second set of eyes since he just got out the hospital earlier last week. The front seal needs major work. Fortunately, dow 795 doesn't cure the same way regular silicone does and can be applied on existing and bonding to it. There isn't the horrible toxic eye-burning release either. It's rather pleasant to work with actually. I can't imagine how long it took to do the main window (21' x 8' x 5.5") on my friend's two tanks. That would be near impossible...
