I have a vinyl lined 28k gal SW IG pool. I just got my test kit today. I have not been able to raise my Chlorine level. I would like to share my numbers and get some advice on what to do. Someone told me that Phosphates can deplete Chlorine, so I tested for that too.
Here are my readings:
Free Chlorine: .19
Total Chlorine: 3.61
Total Alk: 104
Calcium Hardness: 324
Phosphates: 1,000+ ppb (the test does not measure ppm)
Nitrates - Not tested. Should I buy a test kit for them?
