Looks like the plaster is being eroded.

Do you add solid chlorine, especially dichlor or granular trichlor to that area?

Just uploaded them sorry

no we use chlorinator . Tabs are never in pool

what would cause that?

OK -- can you post a full set of water chemistry test results using your own test kit?

 

[Jen102100]

Chlorine is really high-10
Ph is 7.5
Alk-105
Hardness 475
Cy acid 140

Those are from what type of testing kit.

Are the eroded spots only in shallow areas that may be dry when the pool is winterized?

Went to pool store for those numbers… no they seem to be all over and getting worse. Could it be from unbalanced water? The steps and bump out are the most troubled spots. Feels like sandpaper

You need a proper test kit. I suggest the TF-100/Pro or Taylor K2006C. A proper test kit is needed to get the accurate water chemistry results needed to follow the TFP protocols.

Once you get your test kit, run a full set of tests and post them here.

Plaster erosion is normally due to low CH, low TA, low pH, and / or the use of granulated acidic products in the area of erosion.
