My salt level dropped below suggested levels probably due to so much rain water dilution and draining so I added a couple bags to get back up to the 3000 ppm range. However I was doing a full water test today and while all other levels are spot on my CH is about 5x the recommended range? I tested again and got the same reading. Any chance this is due to salt additions? I checked CH about 3-4 weeks ago and it was spot on range. I did have to slam the pool due to algae a few weeks prior also.
