Had minor algae, started off w/high CYA, removed 30% water, CYA reduced after refill. Then began shocking w/bleach. Algae gone, did the overnight FC test, passed. Now the CYA is back up to 100. This is a SWG plaster pool. Do we need to remove water again? I know to add acid to lower pH and maintain around 7.0-7.2 until TA down to acceptable range.
Thank you!!
here are current readings:
FC 11.5
CC 0
TC 11.5
pH 7.8
T/A 130
CH 350
CYA 100
