I have a relatively new saltwater spa. I seem to have adjusted the SWG to maintain a stable level of FC (i.e. 3 hour run time at 25% for 2,200 gal. spa). However, during the past month I have added 25 lbs of salt to maintain the recommended level of 3,400 ppm. Since the spa has an auto cover & is opened maybe for an hour every other day, I am curious why the salt level is dropping. Is this normal?
Thank you kindly.
