So I still consider myself a "new" pool owner and need some help. I have a tft-100 test kit and tested the pool today. I got a FC of 2, CC of 0, pH of 8, Hardness of 275, alkalinity 30.
I took a sample of pool water to the local store and got a huge discrepancy with FC 0.86, CC 0.15, pH 8, Hardness 148, alkalinity 35.
I got both samples about elbow deep. Now the home test I got from a less deep part of the pool but don't think this could account for the big difference in chlorine and Hardness.
Any help would be great
For ref, I have a Jandy Aquapure with AquaLink salt water pool ~40,000 gallons I think.
