Thanks for a he reply. My original plan was to go all the way from front to back with overflow, but saw an opportuniy to have more planted areas and 3d stuctures.
When I looked at it when I first completed the 8' window on a 10' tank. I was amazed at the visability to the rear corners.
The plumming below, filters, outside drain direct the box locations. I keep getting ideas for the next one.
As far as the glass mount. I will finish the frame with 3/4 maple. When finished it will be doubled 3/4 maple. Ran out.
