I posted a thread in RD for this but wanted to add my query here as well.

My tank was made from a standard 300DD. I had the corner overflows removed and then one end drilled for a custom overflow to do a peninsula setup. Now I need to plug the 4 holes drilled in the bottom. My plan was to use bulkheads and a PVC cap but the bulkheads hit the frame underneath. I was told to use glass and silicone on the top and bottom but curious what type, thickness and what silicone is best. I would assume tempered would be ideal but not sure if I can get 2 4x4" pieces of glass cut. From my furniture days, I remember getting custom tempered was an ordeal. I was told glass will adhere better than acrylic as well.

TIA.
