<6 month old pool, started up with TA ~120, brought it down to 80..then added borates and finalized cya, TA rose to 140....have been dropping ph and using acid for last 2 months (gone through at least 5 gallons of acid in that period), tested yesterday and TA was 170. Note that our pool has SWG, autocover, and intellichem to put small doses of acid in every 30-60 min. Our CH levels have stayed relatively reasonable ~320. Wondering what the next step should be....keep pool uncovered and connect some kind of aerator to returns? or just wait several more months to get TA down?
