I have what I think is a gunite/plaster pool about 22,500 cubic feet. I have noticed over the past couple of years that it is using losing chunks of plaster, particularly on the steps in the shallow end but also in the deep end where no one ever stands. Can anyone help with:
1) what the cause of this is
2) what I can do to prevent it in the future
3) solutions to fix what is there or replace what is missing
Some pictures are attached below.
Data from my pool is:
FC 5-10
TC 5-10
pH 7.5
TA 100
CH 190
CYA 90
