Resealing tank

[Cliff]

I would suggest better safe than sorry. If it was me, I would replace all of the outer seals in the tank.

I have always done that in any used tank that I've bought if there was one or two spots that looked like they "could" leak in the near future.

You'll only be out a hour or two of your time and some additional silicone.

Just a suggetion

Agreed, but in this case the existing seal is 100%, just the wrong color But I am doing the whole thing, just to do it right...

I can't see any problem resealing a tank if the old bead is removed (nor why it would be weaker). When you remove the old joint you're just removing the filleting (unless disassembling), the actual thin bond is still there between the two pieces of glass. As for sticking, even if it didn't to the old silicone, it's only the ~1/16" seam, bead is still going to extend over either side and adhere to the glass.

sry for hyjacking your thread but if i reseal a tank should i redo the seam around my overflow or will cutting it off (silicone)at the overflow be safe for the bottom back seal or do i need to remove the overflow before resealing?

I would remove the overflow box, reseal and then re-install the box.
