So i discovered that my 55 gal was bowing A LOT cuz i got it used with no center brace and i didn't know i needed one! so i just drained it and i have all my fish in two rubbermaid containers. I put HOB filters and heaters in both of them. My question is, how long can i leave them in there cuz i'm gonna have to go buy a new tank and it is gonna take me a while to buy it and set it up!!???
