I have a 2 month old pool, completed in October. I live in the South East and will keep the pool open (technically), as my spa is located inside the pool. I'm trying to balance water that has a temperature of about 48 degrees and am having trouble keeping the LSI under -.50. At ideal PH (7.5), Akl (100), and Hardness (180) the LSI is -.60.
Which of the three attributes should I try and raise, if any? PH? Akl? Hardness?
