Have had the new system up for two weeks. compupool36 on a 12000 gal pool. ph 7.5, cya 50, alk 100 salt 3500. Running the system at 40% for 6 hrs/night with no use of pool yet. My cl is only around 2. It seems it should be higher with a 36 at 40%. I saw you recommend higher cya levels. Any thoughts?
