Patch over a crack in glass? Or replace.

[Delphinus]

is it possible to patch over a crack in glass?

I have a crack in a sump. The crack is completely contained in the first baffle; and is vertical. The baffle compartment is roughly about 3 gallons in volume. I have enough scrap glass that I can patch over both sides of the crack.

I have patched over drilled holes in the past but never a crack itself.

Is this a bad idea? I.e., is the only hope for "real" salvage of the tank by replacing the whole panel? (Which is obviously possible, but more work due to needing to remove and then later replace the baffles that are there already.)
