Question About Scaling

[alanrmeadows]

Any ideas as to what type of scaling I am dealing with?

FC 4
CC 0
TC 4
pH 7.5
TA 100
CH 260
CYA 30
17,500 Gallon Fiberglass Pool
South Arkansas

See attached pictures.

Thanks

Are those raised from the surface?

In the picture that seems like what it looks like when the gel coat has worn away ... I have similar looking things on my slide.
