How to "fix" crack?

[Tfain]

Can I just put silicone over it and turn the tank around and cover it with LR?

Are you talking about a crack in the tank or crack in your LR?

you'll have to silicone a sheet of glass over it to keep it strong, but even then its hard to say if it will last. the only really way to fix it is to replace the whole section of glass

With glass tanks sometimes its just cheaper to
Replace the tank than the glass because you have to strip away all of the old silicone then put in new silicone and If you don't get all the old out it won't adhere properly

How much is it to replace the section. It would be a 6'x20" piece of glass

Depends on the thickness,

If you're going to take the whole panel off, use a guitar string ( use it like you're cutting cheese,a sawing motion back and forth)

Make sure you clean off the old silicone with a razor blade and acetone the surface before re-applying silicone.

Also make sure to use the correct type of silicone approved for use in aquariums

Try posting up a pic of the crack

exactly, regular glass isn't really that expensive, mostlikely you'll need 3/8" glass which will probalby run you about 6-8 a square foot.

and like audifusion said, make sure you clean the old silicone off, silicone doesn't bond well to already cured silicone
