I bought this tank used and need some pointers. The tank is 72(L)x25(H)x20(W) and looks like it has been resealed before but they did a terrible job. I'm working on resealing before setting everything up and my question here is when resealing the tank should the top trim be resealed as well or can get away with just resealing everything else. I'll post pics to show what I'm talking about.
