Horizontal crack behing pool spa (w pics)

[consoleman]

So during a short freeze on of the tiles fell off. I then noticed a horizontal crack running along about 6 tiles. I then removed one tile and found a crack on the wall behind it. I'm going to remove as many tiles as it takes to find out how long it is.


There is a crack on the top surface of the jacuzzi that could have been the cause of this (I just bought this house in November so I think it was neglected). My guess is the a have to dig the crack out and build up the surface with ez patch no 1 (plaster I think)?
