Hello,
My neighbor contacted me and asked me if I could assist her trying to figure out what these growing white lines were in her pool.
Her non-swcg plaster walled pool chemistry is FC 8-9, Ph 7.7, TA 80 and CH 200. I went over to take a closer look and found these to be hard crystaline accumulations of what I believe to be calcium depositing. It protruded from the wall but seemed to originate out of the tiles. I was able to scratch it off.
What do you think caused this? Recommendations?
Thank you,
Max
