Tile/Wall Repair

A couple pieces of tile fell off my pool wall near the steps. I'd seen that the grout needed some repair but forgot to do it. When the pieces fell off I noticed a big crack behind the tiles!

So my question is, do I look up (or get a book on) grout/tile repair and go about repairing the tile or is it likely that I've got a MAJOR problem with the crack there and need to get a pro in.

The crack (at least the visible part) is above the normal water line.

Any suggestions?

Think I'm gonna just pump some liquid nails into the crack and apply adhesive to the tile and reapply/reseal the grout. I can't imagine being able to fix it better without tearing up the cool decking so this will have to do I guess.

Do you have an update on your problem? I have the same issue although mine is not nearly as large of a crack as yours but is about 10 tiles long and runs horizontal.
