The pool was installed last year.
When in the pool a gap can be seen under the coping where it sits on the top of the fiberglass pool.

Should I seal it so if it does overflow it will just flow onto the deck and not in between the coping and pool? If so what is the best way to do it?
 
What are you thinking of sealing the gap with?

Better to stuff foam backer rod in the gap. It comes in various widths.
