I drained my pool in two waves (I know I probably should have just done it all at once), and had a portion of the plaster exposed for two weeks. I’m in AZ and the hottest it got was 80. I finished emptying it today, and when I went to hose it down, the upper section that had been drained earlier started showing these moisture lines(not even sure what to call them?) inspected closely, there’s no visible cracks where the lines are. Should I be concerned about refilling the pool? I’m not sure if these are micro cracks that could lead to some sort of structural damage or leaking? From records provided to us, our pool hasn’t been replastered since 2002, and the CYA was over 500 so I needed to drain it after two summers of spending so much $$ on liquid chlorine….any advise is appreciated.
