New 55 gallon

[mfergusonjr]

Picked up a 55 gallon on craigslist this morning. It looks to be in good condition, however, as you can see in the pic there isn't a bead of silicon in the corners. I've filled it 1/3 with water and it's holding fine so far. Should I reseal the corners? It hasn't had water in it in a year but held fine before that.
What are your thoughts?
