Folks,
See Pic. Pool is covered in mostly 'sandy' colored discoloration. Some 'turquoise' shading also in areas. I can remove it by scraping....but...am I removing scale sitting on top of the plaster or the plaster itself? Either this has been going on year after year and has gotten so bad it's unmistakable now or something very different has happened in the last 12 months. Pool is 23 or so years old. Pool heater is working and appears to be ok, that is 11 years old.
