Bought a tank from a co worker, now im trying to get the crud off the glass. *** noticed there are some bubbles in the silicone bead on the corners. Its a 55G All-Glass tank built in 1987. old owner said it did NOT leak when he took it down. Id like to re-do the corners with new silicone. My main question................can the tank stay assembeled and just trim off the inside edges, or does it have to come apart to get the " sandwich" effect where the two glass panes come together??

the sandwich effect is preferred.new silicone doesn't stick to old very well.*** got 20yr old 55's that still hold water and has air bubbles in the silicone.i would test fill it outside if you've never seen it hold water.if it holds then i would use it.

If you want to reseal, you need to remove all the silicone from inside the tank, not just the corners. If it doesn't leak, as it is I would leave it. However, if you are concerned, by all means reseal.

Yeah, if the tank is structurally good, you can get away with removing the inner bed and leaving the silicone between the panes.

The black thingies supposed to be knifes :) First cut all the way to the glass side, Then carefully Cut awat the trim pulling it away as you go, but leaving the seal between the glass panes intact. The use a razor blade to scrape off any left silicone and apply a new bed (green).
