Hey Doug! You're one of the guys I recognize from way back (on RC too
)
Do you happen to have a pic of your tank? I did a quick search for your username but didn't come up with any posts that were blatantly obvious in my admittedly hasty search. Also, do you have any pics of your skimmer set up? I haven't actually seen a Tunze skimmer set up so I'm not sure how the brackets are configured and how they function.
And good to hear that worst case scenario I can get away with 1/2" glass and no brace (although I'd prefer the 3/8").
