Hey everyone. Found this white splotchy areas in my blue-ish pool today.
This is the best pic. On a bench under my waterfall.
On a step between horizontal and vertical parts.
The areas are not any rougher than the pool and seem to be in areas in corners or vertical to horizontal changes.
Current test data:
Oh 7.9 (added acid
Cya 60 (+25 oz of stabilizer then I ran out)
I tried searching for white spots on pool but can't find anything definitive.
