Pool builder put 2 bottles of acid in the pool yesterday (i found out today) I tested it twice and its at or below 7.0 (taylor kit). The plaster (pebble) is less than a week old. Should I raise the PH as the CSI now says corrosion likely or run the waterfall and airate (sp?).
PH- >= 7.0
TA- Dropped from 230 to 125
CH- stable at 310
CYA- 45- he needs to add more conditioner
