A recommendation would be that as soon as you notice something irregular about your tile, you should do something about it, ie hire someone to come out and work on a remedy. The longer you wait, the more substantial your issue can become.
Tile serves cosmetic purposes on a pool. It also allows for easier scrubbing of the scum line (without it, it would be hard to keep the ring around your pool clean). Without tile, a pool doesn’t look as good. Once a pool has tile and it begins to crumble and fall off, it’s even worse.
