New pool here with a Jandy Aquapure 1400. As the title describes, my salinity was showing 3700 (3500 measured at the pool store) prior to adding the prescribed amount of boric acid yesterday. After adding the acid in the deep end and brushing, the salinity reading jumped to 4200ppm and stayed that way for > 12hrs. The next day (today), it's back to reading 3700. All other chemicals were within range except for a high (20) FC reading.
Anyone have an idea as to why?
