Hello; I likely would also run an extra line of silicone on the inside of the tank at that corner. May not help much but sometimes I feel better doing something.It looks like a chip and not cracked... not cracked is a very good sign. I think you can use it. If it is NOT cracked, (yet) either remove the chip(s) and fill the gap with silicone or, use silicone to glue the chips back in place. I think it might be okay!
He would need to remove all the silicone from the corner in question to do this as silicone does not adhere to silicone. Whether or not that is worth while & relation to the risk involved,or feasible, is something to considered carefullyHello; I likely would also run an extra line of silicone on the inside of the tank at that corner.

Hello; To reseal a tank which has already leaked or has been taken apart I agree with your comment for the most part. New silicone over old will not always seal for a leak. Not clear the OP has a leak as yet. I was thinking more of potential reinforcement of the structure. A bit of wallpaper corner siliconed on the outside ought to help with that as well.He would need to remove all the silicone from the corner in question to do this as silicone does not adhere to silicone.
