Hello, I am trying to buila a octagon acrylic aquarium. I have it all taped together and I was wondering how I would hold it all in place while the silicone cures? I read a few threads on this subject and they all are about building rectangle tanks. I did all the measurements and the tank will hold about 9 gallons. Does anyone have any ideas on this? Do you think that it would be easier to glue the pieces to the bottom, then glue the piece to eachother? or the other way around? Thanks for any and all advice.
