As a new pool owner, having an issue. Pool has been up and running for 2 months now, but my SWG is not producing enough chlorine. I took a sample to the pool store around the corner, NPS Pool Supply which I am told is the best option in Las Vegas. After testing, they told me all the levels were perfect (ph, chlorine because I had added shock, CYA...) except my salt level was low. The digital readout where my pool equipment is shows 3.1 (3100 ppm), and the pool school guy told me to keep it between 3.0 and 3.2. The test at NPS said it was at 2.2. I'm running my SWG 10 hours a day, 80% and not even close to keeping up with demand of low/moderate use.
I guess my question is, which do I trust? Could the readout at home be out of calibration/never calibrated properly? Would low salt be a reason my pool won't generate enough chlorine?
Thank you all for help.
