So they just finished my pool on April 20 and we filled it on April 21. I have wet edge signature matrix in brilliant blue. Everything has been going great until this morning I walked out to it and realize that there was something sitting on the bottom of the pool. Upon further inspection it looked as if it was a piece of the bottom of the pool. I immediately jumped in and swim down to it and found that there was a almond imbedded in the plaster of my pool that had turned loose and popped the plaster up. I have called my pool builder but I have not received a call back yet. Has anyone heard anything like this happened before?
