Greetings, I just picked up a 75 gal. Oceaniac tank. The dimensions are 17 3/8 x 23 1/2 between the center brace & inside of frame. Looked online & can't find the glass canopies to fit this tank... Any suggestions? Thanks Gerry Wojo....
I would just go to a glass shop and have them cut to size. You can buy the hinges and little handles on dr foster and smith for pretty cheap. If you go the acrylic route it'll probably cost almost as much because you have to buy acrylic that's fairly thick. If it's too thin it will warp.
Acrylic will warp if used as a lid where it's not screwed or glued. I would use glass - it's not too expensive for that size and would be permanent. You could even design to have clean holes on top for feeding.
