I've worked hard since opening the pool June 1st to get my pool water balanced (ph, total chlorine, alkalinity all good, metals out and filters degreased, washed etc., algaecide in (non copper)) but I've noticed a slight cloudiness that lasted all day-I had recently added 7.5 lbs.of baking soda to raise my alkalinity. Unfortunately it started raining mid afternoon so checking clarity b4 sundown was difficult. I'm leaving home for 4 days tomorrow at 4 am. So I've decided to leave the filtration pump running continuously and set my salt chlorinator to run for 5 hrs. per day. Assuming my Polaris Auto Clear Plus system is all good and salt levels good (they are), is this sufficient for four days. Should I ask my housesitter to add an amount of muriatic acid? I sound like a nervous nelly, but 2 years ago when the pool was new I made some $$$$ mistakes. Oh yeah, I'm a newbie here. Thanks in advance for your help.
