Thanks Wayne. I'll save the info for the future. I got lucky this time.
Drained the water down to about 5 inches (reserving a lot in a plastic tub I
where I also put some live rock) and the leak stopped. Dried the ouside and
siliconed the seal all the way to the top. Siliconed the inside seam from
1/4 inch above the "drained" water line to the top. Let it dry and replaced
the water, changing about 30 gallons to fresh. No leak so far.

I had a small bubble in the silicone in between the glass on the front left
corner, that was fine until a bristle worm dug through the outer silicone
making a path to the bubble.

So, using a hypodermic needle, I inject potassium silicate (sodium
silicate would work too) [preferring that it be on the high Ph side with
the addition of potassium hydroxide, or sodium hydroxide] into the corner.
A little fine silky beach silica sand helps improve the effects of the
silica jell.

Hi all, my tank just sprang a leak. It is in the bottom rear corner,
where the side and back glass come together. Maybe 1/2 inch from the
bottom of the tank. Does anyone know of a way to fix this without
draining the tank and removing everything in it? I have no practical
place for the live rock and sand, although in theory, the fish could hang
in the isolation tank for a few days.

Thanks, Mike
