OK so I'm at it again today i decided to remove the back panel of my 24g nano cube because it has a crack for years but im going to drill the back for a over flow so im going to replace it with 1/4" acrylic. I had to first start by takking it down this was my hospital tank...
here's the tank at the start already drained

here is the the crack it held just fine with a little silicone

i removed the false back next this was way to easy it all most fell out and the silicone pealed right off the glass here it is out next to the tank

next thing i did was to try to remove the top ring lol this thing is glued on from the top edge of the glass
what a B#$#@ so scraping that idea i decided to cut the top trim out so i could remove the back glass
i tried to cut the seams but could not get my knife in between the two pieces so i hit it with a pair of hammer
and then took out the pieces so here it is finished you can see where i cut the top trim (witch you wont be able to see it from the front)


tomorrow I'm going to go get the acrylic and get it installed
