Opened my pool up this year a week ago, after finally getting my new sand filter up and running. 18 x 36 kidney shaped pool. Removed cover. Filled pool up to desired level. Poured 2 1lb bags of pool time 4 in 1 shock plus treatment in on the first day. 2nd day poured one more 1 lb bag in. Algaecide placed on the first and 2nd day of opening. This was one week ago. Checked the chemical balance today and this is what i get. pH 6.8, total bromine 10, free chlorine 3, total alkalinity 180. I added some pH increaser today, but not real sure about how to correct the other issues. I have not put any bromine in the pool to my knowledge.
So how can I correct the alkalinity and bromine levels??? Thanks for the help in advance!
