You seem to have extensive knowledge of the ends and outs of this hobby. I will not hesitate to follow your advice. I have been on this forum for some time trying to get info on spacers for my 135G build, some say spacers, some say no spacers, but common sense says plastic zip ties will work just fine. As for the extra bracing in the corners just makes sense to me, maybe unsightly but for me as brand new to fish keeping its solid construction (peace of mind, my first go at gluing the glass together was a total disaster spent 2 weeks cleaning the silicone off the glass) you were saying that you installed 2" strips in the corners for extra support. my glass guy here cut me 1"x1/2" strips that I plan to glue 2 pieces together and to install a pair in each corner. I just subscribed to your U-TUBE channel and plan to "power watch" all of them. THANKS for the info Alex
