So i have 21 x52 round with a sandfilter and ionizer hooked up i usually only check my pool once a month usually never had algea or any problems but we have got a ton of rain so i decided to check it fc 0 which is normal with the ionizer ph is 7.8 and alk say 140 an copper reads within the correct level cya is at less than 30 should i add muratic acid like pool math says cause it seems to be alot or just balance the ph back to 7.2 7.4 range an cll it good?
