so we just acquired a used 55g tank for 15 bucks. one of the corners has a couple chips in the glass but nothing that reaches the seal at all. the glass is super thick, too. my concern is that it does not have the center brace piece. it's not missing, it seems it just was not made with one. without that piece I can't use the 2 glass lids from my 20g tanks that the 55g will be replacing. is there a way I could safely attach a DIY center brace to use my existing glass lids? if not, are there lids made for a tank like this?
