Do you actually swim in that water?Do you know off hand what fiberglass was used to line the pool? If it’s not Vinylester then the chances are good it’s flaking bubbling of the gel coat, especially if your pool temperature goes into the 30s and higher.
That was the reason mine bubbled, and I had to do a re-lining - went with vinylester and everything seems great now, even with a water temp of 36.5 yesterday
