So I managed to find my self a 1 year old tank in the size I wanted 5x18x20 with stand and hood.
I decided to redo the seals as it looks like they are starting to peel a little in places and the bracing just to tidy it up a little. I am half way pulling the tank apart However when I got down and had a closer look I noticed that the end panels aren't entirely square they are about 2mm out at two of the corners on the bottom.
What do people think about this? I was really hoping that I didn't have to completely rip the thing apart as I am not sure I would be able to successfully put it all back together. I have seen many videos on how people do it but they are usually only small tanks nothing of this size.
