Usually the result of Sanitizer (Clorine/Bromine) being at too high of levels, too often

How was the sanitzer fed to pool before the salt system?

Did you shcck through the piping or use chlorine in the pipes over the winter?

We changed systems very close to when we first moved in. We did know the previous owners and came for the occasional swim and yeah, you could tell the water was very off balance. Shower was a must afterwards and if you got your vision back within the hour of getting of the pool - it was a comfortable swim - haha. It wasn't that bad but there was stinging involved. Thanks. We can be more aware for the new plumbing.
