Just started our third season with a gunite/plaster pool and this year the plaster has become a bit rough. I loved the smooth finish the first two years and yesterday after the kids swam all day we had a few toe blisters and complaints.

This roughness seems to have developed during the off season. It is not terrible and I have certainly been in pools that are worse. But annoying just the same.

I pay a lot of attention to the pH and use about a gallon of acid a week to keep it in range. We have a SWC...

Questions -

1. Could this be related to salt in the water?

2. Is this a normal condition that gets worse over time?

3. Any ideas on how to improve the surface?

Thanks .
