Has anybody ever put 2 separate pieces of glass on the front of a plywood tank to get extra length. Combining 2 72" pieces to make a 12' tank or 3 72" pieces to make an 18' tank. There would be a piece of plywood where the two ends meet, in the middle, to silicone to. The idea is to make a 144"x12"x12" tank without buying a 144"x12" piece of glass or the possiblity to go longer if able to. Any insight? Thanks in advance?
