I have never seen anything on how adding CYA effects a pools chemical balance. It is an acid, so how much does it effect PH and ALK? Does anyone have a ratio of what to add per pound for every pound of cynaric acid added? This might be difficult since it takes so long to disolve. I usually add 8 lbs of CYA to SWG new pools over the first week (thats for a pool of about 25,000 gallons). It would be nice to know a set amount of PH or Alk increaser to add with it.
